Ecarke 220W Portable Power Inverter Compatible with Makita 18V Battery (Tool Only), DC 18V to AC 110V Power Station with 1 AC Outlet, 2 USB-A, 1 Type-C & LED Light for Camping Outdoor Emergency

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 battery Inverter off (sleeping) 7 micro amps 65 years Inverter ON (no load) 0.11 amps 36 hours Inverter On (light 100%) 0.20 amps 20 hours Inverter On (light 75%) 0.17 amps 24 hours Inverter On (light 50%) 0.15 amps 27 hours Inverter ON (16 W Bulb) 0.93 amps 4.3 hours Conclusion First, 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!

Awesome little unit. Using a 40w heated lunch box, and running a 5ah batt, I'll plug in my lunch as 915-930, it'll be hot by noon, and I'll still have 1 bar left on the battery. I don't get quite the same run time on an 80w box (expected) but that's alright. Lunch gets hot, overdraw protection kicks in and shuts down the inverter: perfect. Used it once inside my duffel (oops), and the fans kicked on when necessary. I'm thrilled this works so well.

Worked amazing filled a 18 inch tall queen size air mattress and charged a phone while doing it with no issues and very little battery life used

First off only half the buttons light up. Second it keeps shutting off cause the connection is extremely weak. Mine might be defective but I don’t wanna order another one and play the waiting game . There’s other brands . Grate idea horrible execution. And the light is good up to 6 feet. But it’s ok good for up close . UPDATE : it clicks in now . Had to slam in the battery in and after that it now slides in fine . Not sure what that was about but it works . This is a definite must if you have unused batteries laying around like me. 4 stars cause the buttons only light half way but still gonna keep it. The price is reasonable.

This product works very well, I do recommend it.

For a guy like me who has tool batteries around anyway, this is a very straightforward and cost effective way to keep the WIFI modem (and/or the laptop) going and the phones charged during an extended power outage. It will be nice for outdoor activities like camping and boating as well.

Took this on a camping trip this weekend and I was able to charge my phone/watch, used it as a flashlight when walking to the bathroom, and used it to inflate my air mattress. Very handy!! Let other people borrow it and they loved it as well! Just make sure you have your dewalt battery since its sold separately! Highly recommend!

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.

Super pour le camping ou pour urgence

Me proivieron mi opinión producto malo! Por decir algo

Très pratique et efficace. Super.

Worked.

Didn’t work at all worked for an hour and then it stopped working. Can’t find how I can return it. Not too happy.
