Portable Power Inverter Compatible with DeWALT 20V,Ecarke Real 200W Outdoor Generators with 2 USB&Type-C&AC,DC 20V to AC 110V Portable Power Station, Charger Adapter Battery Powered Outlet(no

Sooo I was skeptical, but I bought the double set of inverters. DANG, I immediately used my fully charged 8ah (generic) battery to try the light. It was on high for 5 bites and showed no signs of dimming! I’m impressed! Good job! I was using the other to charge my iPhone 17Pro and it was awesome!

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!

Worked.

Ended up returning the item because it didn't power anything or held a charge.

Très pratique et efficace. Super.

Camping

Works amazing, easy power source when you have no power. Lightweight and charge last a long time. Excellent value, easy to use.

Has worked well for my use. Powered cell booster at deer camp for 12hrs on 2 5amp hr batteries. Runs very quiet

So far it works like a charm. Came already charged. It’s small and compact. The directions are very easy. And it doesn’t stand out. It charged my Apple Watch and 45 minutes.

Turns off frequently if only using the on-board light since it will have too high of a current draw. Has to have at least one other load (something charging).

It functions as described. Using the 120 volt outlet is something I would recommend using only bin an extreme emergency as it depletes the battery fairly quick, although I haven't actually used that function because I didn't buy it for that reason. I do have other battery powered devices that also have a 120 volt outlets and I did use the 120 volt outlet. It depleted the battery in a few hours. That's not unusual for any battery powered device. The flashlight is very bright. The other outlets function very well. Its size and weight are great for camping making it easy to take with you under any circumstances. Its a great item to have during extended power outages.

So I bought this as a blue collar worker to use with a heating pad so I could keep warm during the winter. Plan was to put a big battery on it and wrap the pad around my torso under a belt. This thing works pretty well but I think something is wrong with the voltage as it fried the heating pad after a day and a half of usage and it screetched the entire time it was plugged in :( i will say that the flashlight in it is very nice and bright with variable dimmer. Great for charging phones but don't rely on it for anything heavy or expensive. I will say that I also play pokemon go in my freetime and have 2 devices and a automated token spinner plus electric hand warmers that I charge all at the same time(I have a charger hub i bring with me bc I'm extra like that) so I'm charging like 5 devices plus friends/GFs phone
