Ecarke 220W Portable Power Inverter Compatible with Makita 18V Battery

I routinely use backup lighting around the house for repair projects, interior painting, or craft projects that need good strong lighting....as well as when the utility power goes out. Many years ago I bought a pair of photographic light stands with photoflood reflectors that accommodate typical screw-in light bulbs and provide a nice even flood of light on the subject area. They're my go-to lights for nearly any added-light need. In recent years I've switched them over to 1600-Lumen LED bulbs (100-watt-equivalent) that draw just 16 watts. The light stands are particularly good at accommodating light placement for good coverage...their only disadvantage is that one has to plug them in, which often requires the hassle and trip-risk of extension cords draped around the floor, and they need backup power if the utility is down.WELL...solution at hand. With the little Ecarke Portable Power Supply 200W Inverter with Makita-type battery added to my light stands, my need for extension cords is resolved and they even work when the utility is down. Now I just grab the light stands and inverter/battery when I need added light...so much more convenient than extension cords, and so much better light than typical portable battery-powered lights!As a test, I fully charged one of my 4 Ahr Makita 21V knockoff batteries to see how long my 16 watt (1600 Lm) LED bulb would last. To do the test, I hooked up a professional-quality ammeter between my battery and the Ecarke Inverter to see the exact amp draw of the Inverter under different conditions including the use of the internal light at its 3 levels. The life can then be easily calculated from the battery Ahr capacity without worrying whether my battery is a good or bad battery. Here are the results interpreted for a good 4 Ahr battery:Condition Current Runtime on 4 Ahr batteryInverter off (sleeping) 7 micro amps 65 yearsInverter ON (no load) 0.11 amps 36 hoursInverter On (light 100%) 0.20 amps 20 hoursInverter On (light 75%) 0.17 amps 24 hoursInverter On (light 50%) 0.15 amps 27 hoursInverter ON (16 W Bulb) 0.93 amps 4.3 hoursConclusionFirst, when the unit is turned off, it draws essentially no current; I would say that it doesn't need to be removed from the battery...but it does need to be turned OFF.Once the unit is turned ON, it draws a modest current, even with NO loads attached and NO internal light ON. It can be left in this condition for a while, but it can totally drain the battery in a day or so.The internal light is quite bright and is good for about 24 hours on a 4 Ahr battery...the 3 levels make a small difference.With the plugged-in 1600-lumen 120-volt LED bulb, the unit drew almost 1 amp, giving around 4 hours of use...a very useful time for many projects. And this can be easily extended by 2x by using a smaller wattage LED bulb.Bottom Line: Very useful product...highly recommended!

Our internal battery for our ION Pathfinder speaker was no longer working as we could not use it without plugging it in to an outlet. We have events that cannot always have that access and need to be mobile. Ordered this item and what a lifesaver that we can still use the speaker. It was a great save for us and we can also use it for backup power source when we lose power. It’s a good size and not bulky which is another plus.

Works well, fast charging USB, runs a small fan with no issues.

I’ve been using this portable power inverter with my DeWALT batteries for both jobsite and home use, and overall it has performed very well. The AC outlet provides steady power and has had no trouble running multiple lamps and other plug-in devices at the same time. Output has been consistent, and I haven’t experienced overheating or sudden shutdowns.Battery efficiency has been better than expected. Even during extended use, it does not seem to drain batteries excessively, and I haven’t noticed any negative effects on battery performance afterward.The built-in LED light is a great added feature. It’s bright, practical, and useful for low-light work areas, power outages, or emergency situations.The only reason I’m rating this four stars instead of five is due to the USB charging ports. The standard USB ports do not appear to support fast charging, and the USB-C port caused an issue with one of my charging cords. That may have been coincidental, and I plan to test it again, but it’s worth noting for buyers who plan to rely heavily on USB charging.Overall, this is a well-built and dependable inverter. If your main use is the AC outlet for portable power, it performs exactly as it should and is a solid option for tools, lights, and everyday plug-in devices.

Great small inverter. Used it to charge my phone while out on the boat all day fishing. For some reason the reception is not great and it pulls the battery down during the day. This provides a backup in case you need a charge and the light is an extra benefit.

So far so good. Ready for an emergency if it arises. I got my battery too

Take this with me all the time to car shows. Small but handy to charge cell phones or items that charge with USB cord. One power outlet for electrical use.

The product arrived on June 3rd. After installing a battery, I confirmed the light functioned properly. On July 11th, I tested the USB-C port using several cables known to work, but the device fails to charge anything I own, including my iPhone. The port briefly powers on before shutting down immediately. This process continues and as a result, the device never accumulates charge, and the battery on the device dies. This really sucks as I wanted to like this little thing and found the price to be a lot more reasonable than the official Milwaukee product. I will add video of this issue if anyone request. ThanksUpdated to 3 stars because they refunded my money after I sent a video of the issue. It might be worth a chance due to good customer service and the fact that, if your unit has a working USB-C, everything else functioned well. Build quality was acceptable for the price when fully operational..

Très pratique et efficace. Super.
