Its strong its a must have

Mine came 75% charged, too. Instructions say the first 3 cycles should be: Charge to 100%, then down to 0% -- three times. For a 100,000 mAh power bank, that's a lot of homework. Contradictory instructions. On one enclosed paper, it says "Input port supports charger with fast charging option." On a different enclosed paper, it says "A 5V | 1A charger is recommended if a power adapter is not included." Well, a charger is not included, but a 1A charger is not a 'fast charger' in this realm. It supports fast charging, but they recommend a non-fast charger? Maybe some reviews about the Power Bank charging SO SLOWLY are because some people are following the 2nd paper, trying to charge up 100,000 mAH with a 1 amp charger, lol. Performing differential equations, I calculate that a 1 amp charger would take 100 hours to go from 0% to 100%. And you have to do that three times. I'm sure the intention is to use a quick charger that can deliver 18 watts, 12V at 1.5 amps, to the power bank. Someone just didn't notice the erroneous small-print about the 1A charger they included with the power bank. I do have a quick USB charger with a 100 watt jack. My USB tester says the new power bank will take 12V at 1.5 amps from my quick charger. That's 18 watts as specified. The power bank maybe has another mistake. Printed on the side of the power bank, it says Output 2 is USB 1, whose max output is 12V/1.5A (22.5W). If its capacity is 1.5A, then it's 18 watts, not 22.5. If it can deliver 22.5W [as marketed], that would be 1.875 amp capacity, not 1.5. Round DC connectors -- Everyone raise your hands that will be using the round 12V input or the round 5V output. The faux leather handle is thin, feels like it will tear if actually used any length of time. And when it does tear, the power bank will fall to the floor and split open. It doesn't smell like leather either... Printed on the power bank next to the output jack specs, it also says Cell Capacity 3.7 volts 100,000 mAh 370 Wh; Net Capacity 62,000 mAH 310 Wh. 310W/62A=5V, confirming that the 62,000 mAh is the working 5V capacity. The Marketing Department prefers to provide the internal 3.7V battery specs, not the 5 volt working specs. I can't find where it says what the power bank chemistry is. They should say, so we can research how best to treat the battery, if we care to maximize its lifetime. But the 3.7 volts printed on the side suggests either Lithium Ion or Lithium Polymer. Both are 3.7 volts, but should be treated differently. Directions say best capacity will be achieved when the power bank is charged and discharged 3 times. I never heard of that. Do they really mean to charge to 100% and drain down to 0% --three times? They should specify the desired percentages. In my limited experience, 100% and 0% is the worst way to treat a Lithium Ion, not the best way. I'll have to ask the Artificial Intelligence if there's something special about the three initial cycles. The flashlight gives a nice soft white glow, good for something when the power goes out in the middle of the night. More like a mood light, like a few candles. But you'll still want a real flashlight if you want to avoid tripping over the cat. Besides, the cube is a bit large to use as a traditional flashlight. Press the flashlight button until it comes on. Then tap it to cycle between Dim, Brighter, Brightest, and Blinking Brightest. Update, 2 days later. I spoke to the artificial intelligence. It confirmed that before normal use, the power bank really should be charged to 100%, then discharged to 0%, and do it for 3 cycles. This calibrates the power bank's Battery Management System. I never heard of that either. If the directions tell you to perform that procedure, then your power bank has a Battery Management System. One of its functions is to give a (hopefully) accurate readout of the remaining charge level, hence the calibration procedure. It took almost a half a day, or something, to increment the power bank's charge for each 1% using my 1 amp, slow-charge, USB charger. Until it got to 98%, at which time the charge stopped incrementing. I had to attach my 100 watt USB charger to get the power bank to go up to 100%. Maybe the last two percent are a special situation, and if I left the 1 amp charger hooked up for a few more days, the power bank would have crept up to 100%? The artificial intelligence also said that during the charging-half of those 3 charge-discharge cycles, it's ok to interrupt the charging, and even draw a little bit of power from the power bank before resuming the charge. Then, for the discharge-half of the initial 3 charge-discharge cycles, for a 100,000 mAh battery, it will take a long time to discharge it down to 0%; nice work if you can get it. It didn't seem necessary to inquire about doing a little charging during the discharge-half of the initial cycling. Just say No. And lastly, of the four USB-A outputs arranged in a square, the one in the upper left corner is supposed to have quick-charge capabilities. Mine didn't increase beyond 5 volts, and I assumed the power bank had a failing quick-charge function. But, I purchased new USB-A to USB-C cables (Amazon item# B07T8FR5L9), specified as "fast charging cord," and then the power bank's USB-A came to life and delivered 9V to my phone and 12V to a smaller power bank. No problem. Apparently, the original cables I used were not spec'ed for quick charging.

I am redoing my review I was having problems with my on and off button and only charging to 98% but after banging around the little bit the on-off button now works The thing will charge my phone alone probably 6 times plus a few other things sturdy built holds power good charges things good they could have came up with a better handle but all in all I think it is worth the 🤑

Total game changer in the field, I had guys begging me to share some power and the thing still heals up until the end of the field operations

Tried to send it back didn't show and still don't go to 100 percent when charged... and smelt like it was burning tried to send back and they acted like they didn't want me to send it back did end up charging my phone but still not satisfied... kinda leary on using this bank... so if you have problems have fun trying to return to sender ..¿¿¿¿¿?????

This item works great

Solid battery, good physical size vs. capacity and plenty of plugs - I do appreciate the 12v plug too since I have 2 foldable solar panels that plug directly into these. The one thing you need to know is the advice given here to charge and discharge 3 times - NOT CORRECT - below is why and what you should do: Hey Claude - do I really need to charge and discharge this 3 times? Stop — the advice you're following is for a different battery chemistry, and applying it to this power bank does the opposite of what you want. Let me correct the premise before you go draining it, because the "drain to 0% three times to condition it" ritual will actively shorten this battery's life, not extend it. Where that advice comes from, and why it doesn't apply here. The "fully discharge and recharge a few times to condition it" guidance is a holdover from nickel-based batteries (NiCd, and to a lesser extent NiMH), which suffered from a "memory effect" and genuinely benefited from occasional full cycles. Your power bank is lithium polymer (it says so in the specs — Battery Cell Type: Lithium Polymer). Lithium-ion/polymer chemistry has no memory effect and does not need conditioning cycles. There is nothing to "wake up" or calibrate in the cells by deep-cycling them. Whoever gave you that advice was applying a 1990s NiCd rule to a 2020s lithium battery. Draining lithium to 0% is one of the more harmful things you can do to it. This is the part that matters for longevity, and it's the reverse of your plan: Lithium cells are happiest and last longest in the middle of their range. Every time you take a lithium battery down to a true 0%, you stress the cells — deep discharges cause more capacity loss per cycle than shallow ones. The research on this is consistent: a lithium cell cycled between roughly 20% and 80% will last dramatically more cycles than one repeatedly run 100% to 0%. Deliberately running it flat three times to "make the batteries last a long time" would spend some of the very lifespan you're trying to protect. Worse, a lithium cell taken to actual zero and left there can drop below its safe minimum voltage, at which point it's damaged and sometimes unrecoverable (the protection circuit usually prevents the true worst case, but you don't want to lean on that repeatedly). The "0%" your LCD shows is above true-empty because of that protection circuit — but intentionally hitting it over and over is still net harm. So the best way to prepare this battery is: don't do anything special. There's no break-in ritual. The genuinely life-extending practices for lithium are the opposite of deep-cycling: For longevity, keep it loosely in the 20–80% band for everyday use and top it up when convenient rather than running it down on purpose. Charge it fully when you actually need the full 370Wh for a trip — that's fine, using 100% when you need it is what it's for — just don't store it full or empty for long periods. If it's going to sit between ADV trips, leave it around 50–60% and top it back up before you ride. Avoid leaving it in a hot pannier or a sunbaked truck; heat is the other major lithium killer, independent of how you cycle it. And an occasional full charge is worth doing once in a while for a different reason — not to "condition the cells," but because it lets the LCD fuel gauge recalibrate so its percentage reading stays accurate. That's a gauge-accuracy benefit, not a battery-health one, and once every month or two is plenty.
