Mroace Portable Power Inverter Adapter

Ran an amplifier and pedals for 5 hours on a generic battery. It was great!

Works just as advertised. Using it to power a light post for a theatre production.

Frenkin awesome! 2way power. I can use this to charge dewalt batteries from a portable solar panel. Or I can use the to charge other devices. Plus, a 1-100% power level read out and a flashlight. Great device!

Did what it's supposed to! I tested it on a fully charged 2ah dewalt battery. I hooked a Husky utility light up to it and the cooling fan kicked on about 5 minutes into it. The light lasted about 15 to 20 minutes before it drained the battery and shut off.

They could have made the flashiight a little brighter that is my only knock against it. At the same time, there was no need to integrate one into it.

I bought this to have extra power mobility will out and about working. I always have plenty of DeWalt batteries on hand now I have a combo charger as well with 110V, USB A and USB C so everything can charge on the go!

This really works. Made a different at our 3rd Plant Sale.

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!

I got this to power my Starlink and it’s working great. Tells how low the battery is before it’s dies.

This small Dewalt compatible inverter works perfectly to provide emergency power for when you need it. It features a built-in flashlight, cooling fan, carrying handle, USB-A and USB-C output ports, 12 volt DC power output plus a 180Watt A/C outlet. Check out my review video.

It's fine. In my case it doesn't fast charge the cellphone although it will charge it. Works well with DeWalt 20V battery.

good quality easy to use i recommed it

Great tool!!

Works great!

Cheap and easy.

Really cool works great powers lights and charges surprisingly well

I got this one because it has the 12 volt barrel plug. Ham and scanner guys will appreciate it.

Ran a tv at camp with 5 amp hr dewalt battery and was able to watch a full football game. Great product
