C4 LCD Display Speedy Universal Smart Battery Charger,Battery Capacity Analyzer for Rechargeable Batteries, aa Battery Charger, 18650 Battery Charger

The Zanflare C4 is Zanflare's entry into the Battery Charger market. The C4 is a 4 bay multi-functional smart charger which can charge and analyze NiMH, NiCd and Li-Ion batteries. The C4 is great for anyone looking to upgrade from their non-analyzing chargers. User Interface and Modes Each slot can operate completely independently (for example, slot 1 can be set to charge, slot 2 can be set to Fast Test and slot 3 can be set to Normal Test). In order to set different modes for each slot, you have to insert each battery one-at-a-time, set the mode and then wait a few seconds before inserting the next battery. Each slot can also have separate a current setting. The mode and current is set within 10 seconds of a battery being inserted. Operation: * When battery is inserted, press MODE within 10 seconds to rotate through the modes (Charge, Fast Test and Normal Test). * When battery is inserted, press CURRENT within 10 seconds to rotate through the current options (300/500/700/1000mA for Charge and 300/500mA for Test). 500mA is default. * Once charging/analysis has started, press the individual buttons (1, 2, 3 and 4) to rotate through the display for each slot. Modes: * CHARGE - Basic battery charge mode (300/500/700/1000mA) * FAST TEST - Discharge then re-charge and measure capacity (300/500mA) * NORMAL TEST - Charge, discharge than re-charge and measure capacity (300/500mA) Display: Each also has it's own individual display and can display: * mA - Charge/Discharge Current (Shows the setting, it does not fluctuate in real-time) * V - Voltage * mAh - Cumulative charge * mR - Internal Resistance * Time - Cumulative charge/analysis time Summary and Conclusion The C4 is a nice analyzing charger both in terms of function and appearance. It supports up to 4 18650s simultaneously and can charge up to 2 26650s simultaneously (non-adjacent slots). It can also support charging NiMH and NiCd so this makes it a good universal/family charger. It can also fit protected cells up to about 72mm in length although longer and wider cells like GAs feel cramped and tight. It does not support LiFePo or C/D cells. I like the charge and discharge current options (300/500/700/1000mA for Charge and 300/500mA for Test). I know that some people prefer chargers that can support more than 2A+ for charging or 1A for discharging. However, I prefer charging/discharging my cells at lower speeds for better longevity and less heat. I normally charge my 18650s at 500mA regardless of charger used. The 300mA charging option is also great for people charging smaller cells like 14500s. The charger has good size and ventilation and does not need a built-in fan. When charging 4 cells at 500mA, the charger gets warm. When charging 4 cells at 1A, the charger gets very warm (but not overly hot). If someone wanted to add cooling for heavy use, you could set this until on top of a cheap laptop fan since there are a lot of vents on the bottom. I like the display options and the ability to view actual voltage on top of accumulated charge. I also like that there is individual information for each cell so that I can monitor voltage for all 4 cells at the same time. However, I would prefer if the unit/interface was not "upside down" (design preference). I like that the unit is powered with a proper wall/car plug and not USB-powered. The sliders move well (not too stiff or too sloppy). The power bank functionality works well and charges my phone pretty quickly even on one cell (1A charge). Using cells as a power bank is also a good way to discharge cells (either for storage or testing) without "wasting" energy. My unit terminates charge around 4.16V and the voltage accuracy is within 0.3V when removing cells and measuring them with a voltmeter.

This is an excellent device! It's the best battery charger out there, in this price range...imo. I had a very basic charger before buying this; it basically charged the AA or AAA nimh batteries...nothing else. Plus, I could only charge either 2 or 4 batteries at a time. With this, I'm not limited. 1, 2, 3, or all 4 at a time. I finally NEEDED a charger that was more versatile & told me what I want to know about the the batteries. Well, this charger does it all really. It's great knowing the voltage, charging time, capacity, etc. No having to wonder about the status of the batteries you're charging! Very happy & impressed with this! Seems to be well built, & great quality. The display is very clear & easy to read too. I've been charging at 500 ma...& 300 ma, to be easier on the batteries. The default setting is 500 ma. I'm really into recharging my AA & AAA nimh batteries. Much better & really saves money. I was just tossing regular batteries in the trash can, which is wasteful in the long run. This is definitely the way to go! Thanks for making a great charger like this! Next, an upgrade on the battery tester I'm using. I know exactly the one I want too, from DIYlful. I included some photos. It really shows how consistent this charges. The Duracell did very well. I wasn't even aware they were 2500 maH. Nice.

I live this charger. I have bought more expensive ones, and it does not do what this one does. I tried to rejuvenate almost dead cells with other chargers, and they would not do it. I then put them in this one and used the NOR test, and vola, it brought them back to life. It does have three modes, charge, fast test, and NOR test. Charge does what it says, it charges them, and pretty good also. However, it does not rejuvenate them. Fast test..I used it but I don't think it has much use. Maybe to see what the current capacity is, but I think that it is better to use the NOR test. Nor test. It charges the battery, then discharges it to see what the rate is, wiping out any memory effects, and then charges it again. It does this for 3 cycles and leaves you with a full battery. I tested several batteries this way, and even though they said 5000 ma, they really were less than 1500. I tested brand new IMREN batteries, they said 3500 ma, and all were at least that, if not a little more. But all were within 5 % or less than what they stated. So now I know what batteries to purchase also. They are a little more expensive, but then you get two to three times the battery also. The display is easy to read for me, and the unit is easy to use. It says End when done. You can adjust the charge/discharge current. You also have a dedicated button for reading each of the batteries, not like other chargers that you must cycle through.

I'd been wanting a proper battery charger for quite a while. I had been using a re-branded Tenergy 4-bay universal charger that only did Nicad and NiMH batts. It worked, but took forever to charge batteries (overnight). I discovered these 'smart' chargers that could do all kinds of things and monitor the batteries like my LiPo charger did, and charge all battery chemistries (including LiFe) and looked at a few and found out they weren't expensive for what you get. I looked at the Opus BT-C3100, Nitecore SC4, Miboxer C4 and C4-12, Nitecore D4, and this one, the Zanflare C4. I didn't want to spend $50 for the Miboxer and Nitecore SC4, the D4 didn't have fast charging, the C4 didn't have a 1 amp charge mode, and I couldn't find the Opus for under $45 without having to wait a month or more for it to come from China. So, I got this. $32 shipped to my door in 1 day. Amazing. Ordered Wednesday AM, at my door when I got home from work Thursday PM. Nice. So I like this charger. I'm an electronics and gadgets junkie, so all the functions are awesome. You get all the standard safety stuff like overvoltage, undervoltage, overcharge, overdischarge, reverse polarity protection, etc. I got the charger, wall adapter/power supply, and a 12V car adapter for the charger. It's a 12V 1.5A adapter with a non-standard size jack, so finding a replacement would be hard. On the back is the 12V input and a 5V USB port for plugging in a USB cable to charge things with (Phone, tablet, etc.). They say it's rated for up to 2A. There are 4 slots or bays, and this charger will take every cylinder style battery out there: Nicads, NiMH, Lithium ion in every conceivable size from the tiny up to the big 26650's. Downside is no LiFe chemistry, and you can only use two of those 26650 cells at a time and on bays 1 and 4 only. Otherwise, 4 18650's fit fine. For the features, up front there's that display. Has a really nice deep blue backlight, and shows a battery symbol with horizontal bars showing charge status. Below is the battery stats, mode setting, and the values. Nice. The only gripe is the text is tiny and the viewing angles are horrible. It completely washes out at like 50 degrees. I do like how the backlight always stays on. It's dim until you touch a button, then it goes to full brightness. There's 6 physical buttons, with mode and current up front, and one for each slot that you use to cycle through stats and select slots for current adjustment. it has 3 modes: charge, norm test (I think they mean normal), and fast test. Normal test charges the battery, discharges it, and then re charges it and shows the estimated capacity. That can take a long time for high capacity cells. Fast test does a charge-discharge cycle only. Charge mode gives you 4 current settings available in all 4 bays at the same time: 300mAh, 500mAh, 700mAh, and 1000mAh. There are 4 display functions that display during charging as well: volts (real-time), charge time (hh:mm- no seconds), accumulated capacity in mAh, current setting (not real time), and mR or internal resistance in milliohms. It measures the internal resistance of the cell. That's really helpful in figuring out how healthy your batteries are. High internal resistance indicates a battery that's worn out or low quality, but the best way is doing the charge discharge cycle tests. Discharge currents are 300 and 500mAh. How's it work? Really good! I charged some AA, AAA high capacity NiMH, NiCad, and lithium ion 18650 cells I had lying around, which is going to be its primary role. The charger feels quality and sturdy. The slots have metal sliders that hold the batteries, and they ride in metal slots, not plastic, and the springs are strong which is important for getting a good reading for volts, current, and resistance. The buttons also feel good and solid. Operation is simple. Plug the charger in. Insert the battery and the display flashes with the battery symbol and the current shows as 500mAh, which is default. The charger detects the battery type automatically, but It doesn't show you what it is like some other chargers in this class, which might be handy for a mystery battery with no markings. Push the current button to cycle through the current settings, and use the mode button to cycle through the modes. It gives you a little time to choose the current and mode before it locks in. However, you can change the current setting by long-pressing the slot button and pushing the current button. I really liked that about it since you don't have to take the battery out to change it. You do have to take it out to change the mode though. Pressing the slot button lets you cycle through the information, volts, current, accumulated charge, and resistance. I love how fast the batteries charged. On the old charger it would take all night. On this one it took 1.5 hours for the really high capacity AA's and AAA's at 700mA for the AA's and 500mA for the AAA. At the 700mA setting, the AA's did get a little warm, so I wouldn't recommend that current setting for any battery under 2100mAh capacity. I ran the normal test on some old AAA NiCad and some salvaged 18650 batteries and found that the results were in line with my lipo charger. It takes a long time (6 hours), but really shows how healthy your batteries are. NiCads and NiMH charged to end voltages of around 1.45 and the lithium cells to 4.20. I checked these with my multimeter and t NiMH were 1.4 to 1.5, and the lithium ions were 4.17, well within spec for a charger like this. I tried reviving a dead Lithium ion cell, and it did it just fine. You can use the charger as a "power bank" but NOT when it's plugged in. You can only use it when it has batteries in it, and it takes minimum 2 Lithium ion cells to get the 2A current rating. Pros: Sturdy and well-made Easy to use Handles all cylindrical batteries and chemistries Shows important battery information Has resistance measuring capability 4 charge currents up to 1A for all slots Independently controllable slots Display backlight stays on all the time and dims when idle Revives dead batteries 2A USB port Came with car charger Cons: No discharge mode Display has poor viewing angles No support for LiFe PO4 cells This is an amazing charger for $30 with its capabilities. You pay $15 extra to get the Opus, and $20+ extra to get the Miboxer C4-12 or Nitecore SC4 with largely the same capabilities (minus discharge mode). Great buy. Highly recommended if you charge lots of batteries.

What can I say about the Zanflare C4 Smart Charger / Analyzer? I had mediocre hopes for the C4, assuming it wouldn't live up to its featured hype. But I am happy to say that it has thus far exceeded my expectations. I have lots of NiMh and LiIon batteries. LOTS, over 300. I also have 5 different smart chargers, and a slew of others. So my perspective comes from a comparison of things I already possess and use. My favorite Smart Charger / Analyzer up to this point was the Opus BT-C3400. So most of my perspective is related to that one. The ease of use and setting individual slot configurations is even nicer than the C3400. Additionally, like the C3400 you can set / reset the configuration of each individual slot "on-the-fly" with immediate response. The only feature the C4 doesn't have where the C3400 does is an automated REFRESH mode. Instead, you either manually use the Fast Test (discharge / charge [measure mAh on charge cycle]) or Normal Test (charge / discharge / charge [measure mAh on discharge cycle]) and simply do it manually 3 times to get the same process the Opus performs with its Discharge Refresh program. Sometimes it might be a hassle, other times it is nice to check the value between each cycle to see what kind of results you get at each point. What I've found is that when I need to refresh some old batteries, or ones that have not been used in awhile, where they seem to have lost some of their capacity, I can use the C3400 refresh and then "set it and forget it" until it is done. On the other hand, when I purchase new batteries, I find that if I use the C4 Fast Test manually, I might not need to do a full 3 cycle test to break them in. If the capacity is within 10% of the battery's rating, I then do the Normal test which provides the capacity from the "discharge" perspective (more accurate in my opinion), record my info and move on to the next set of batteries. The C4's display uses a white on blue background so is slightly less appealing than the C3400's LCD display, but is by no means difficult to read. In fact the C4 has a "virtual" battery that is always visible for each slot giving a nice and easy visual status without having to try and "read" something and without having to cycle through the "modes". Though you can cycle the modes just like the C3400 to indicate Voltage, mA charge rate, mAh capacity rate, Internal Resistance, etc. But that visual battery indicating a visual status is also always there, so you know "visually" about how close it is to being done with the discharge or charge state. Effect: I can look at it from across the room and just "know". The C4 appears to have good ventilation much like the C3400. It is a couple inches longer than the C3400, but it really doesn't require much more desk space as in either case you would want to have a bit of ventilation room anyway. I've used the unit on the major battery types (AAA, AA, 14500, 18650, 26650) and used the various current settings (even up to 1A * 4 slots) and the unit itself doesn't over heat or get any warmer than any other charger I own. So the "physical" characteristics are pretty similar. The exception is probably in the slots themselves. Rather than have a multi-tiered slot design like the C3400 has, they chose to simply make the slot "half circle" diameter the size needed for its largest battery support. This tends to make the smaller (AA, AAA) batteries "rock and roll" a bit when trying to place them. It takes more effort in other words. Not a lot more, but enough to certainly realize that it does. The C3400's two tiered system favors AA batteries for the smaller tier as they fit *almost* snug in that bottom tier. The wider batteries fit into the 2nd (upper) tier pretty nicely. So the C4 is not quite as nice as the C3400 in that respect. Additionally, the metal sliders are a little "bendy" (read as weak) so you may have to occasionally bend them to a straight vertical position for proper contact with the negative pole on the battery. Not a major problem, but something they should look at fixing in the future. So that I don't write a novel, I'll simply summarize here with possibly adding comments in the future as they become necessary: The Zanflare C4, much like the Opus BT-C3400, appears to be a solid Smart Charger / Analyzer and performs well. Could there be improvements? Maybe. But nothing major here is needed. I'm thoroughly pleased so far with the Zanflare C4, and the fact it is less expensive than my C3400 is simply icing on the cake.

I've been looking at getting a couple of more advanced Li-Po chargers for over a year, but I just couldn't get on-board with what was out there. I was actually in the process of developing one myself using parts from the auction site until I saw this guy. Judging by the existing reviews of other chargers, I zeroed in on the issue of overheating with them. This unit stands out because it uses an external power brick, which I can see would easily remove at least half of the heat from a four cell charger that is already dealing with charging 4 x 3.7vdc(nominal) at 1amp each max. I'm an electrical engineer, and this is how I would do it if it was my product design. This unit is also able to measure the internal resistance of each cell, and this gives you a good idea of its individual health and power delivery capabilities. I also like the feature that does a full discharge first before charging each cell. In fact, this unit is really like 4 battery analyzers/chargers in one. Each channel operates individually of each other, so if you are going to be testing a lot of cells, you can save a lot of time by simply weeding out the bad cells that discharge way too fast, and have way too much internal resistance. You can free that slot to test another cell and pitch the bad one in the recycle bin. There's no need to waste time on a junk cell that could potentially catch fire. If you are a vapor, this charger makes quick business of separating the men from the boys. It is nice to know that my Panasonic 3400mAh cells are actually rated correctly. If you are in the habit of harvesting cells from laptop battery packs or other sources, this charger is for you. You can go through each cell and get its true rating and internal resistance for matching up with other cells in series/parallel configurations for building battery walls for your next mega-joule search light/laser/EMP "bug-zapper" project, or just general usage for multi-cell and single cell applications.

Works just like my old one. Same make!!

Great charger. I have purchased many chargers in the past including Panasonic, Eneeloop, and EBL brands. None of those has offered the capabilities and battery information of this Zanflare. Below are some of the features of this unit that I value. The included directions don't offer a clear explanation of the 3 modes, but here is what I have found through research and personal use. This unit offers 3 modes of charging your batteries. Each battery slot can be individually set to any one of the three modes. The "Charge" mode simply charges the installed batteries. The "Normal" charge mode first drains the battery (simulating usage till exhausted), then charges the batteries, then re-drains the batteries, then finally recharges the batteries. This could be useful to recondition batteries that don't seem to hold their rated capacity, but I found takes over 20 hours to complete (depending on the mah rating of the battery). The Fast charge option charges the batteries then discharges the batteries then recharges them. I found this option to help rejuvenate some of my batteries that were not holding the mah they were rated for and balances time and reconditioning advantages. With all three options, "End" will flash on the display once charge has been completed and you can toggle through the various display modes to display the mah capacity, voltage, time, etc. of each battery under each respective slot. Finally, this is the first charger I've come across that provides feedback on the condition of the battery when installed in the slot (the display won't indicate that a charge mode is in progress for a bad battery), hours elapsed to complete the charge for each slot and mah hours for each battery (will enable you to label batteries weaker batteries). Recommended current is 500 ma for AA batteries and 300 ma for AAA batteries. Enjoy!

Awesome Units When I clicked Buy I thought I was Only Getting 1 unit But it was for 2 .. I have am using this to test/check 18650 Batteries and it works Well .. took a while to figure out the menu .. press buttons .. done .. Very Easy to Figure out..

Very dissapointed. For a universal charger, it does not charge D type or 9 vrechargebale batteries. and the USB ouput does not work with NiMh batteries. If you're hoping to use this in conjunction with high capacity 2800mAh NiMh batteries to charge your mobile device, look elsewhere. Overall, unless you want to specially charge lithium ion batteries, this is not the best option.

Excellent battery charges and testers. These are invaluable tools for use in cell harvesting and testing large quantity of batteries. NiCad, Nimh, Li-ion.
