Power Inverter Compatible with Makita 18V Battery: Ecarke Portable Power Supply Inverter Convert - Real 200W DC 18V to AC 110V-120V Battery Powered Outlet with 2 USB AC Power Station(Bare Tool Only)

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!

Hooked right up to my dewalt batteries. Used for my heated jacket and works awesome

Product worked out fine. I charged a cell phone from 57% to 100% in 2hours. I also ran a portable Blu Ray player with it. For light power on the go this should be great charging small devices for 2-3 days. As noted not the fastest charge but it gets the job done.

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.

I live in Florida and have a pretty good hurricane kit established. I also have a big line of Ryobi yard and hand tools which means I have quite a few of their 18v batteries. So I thought I’d grab a couple of these less expensive inverters since the one Ryobi inverter I have works so well. And these work well too. The light is bright, USB and AC outlets work as advertised. The only significant difference I’ll mention is these have a cooling fan that comes on when using the AC outlets and you can definitely hear it across the room as compared to the Ryobi which is silent. Not a big deal to me but I thought it is worth mentioning. I’m very happy with my purchase and still give it a 5 star for its form/fit/function and performance.

Review of 300W Portable Power Inverter Compatible with DeWALT 20V Battery: Pros: Solid feel/heft. Has an extruded aluminum anodized housing 109.8v to 110v at full charge, testing with a typical AC test meter Has two receptacles with a good grip on plugs. They're also not mounted loosely in the housing USB ports on the inverter, and also the battery adapter Good fit on Dewalt 1.5AH battery, positive locking Allows user to use a reliable battery pack. Self contained inverters/battery packs vary in reliability it appears. Internal cooling fan 10 min test on a 120v 25 watt appliance resulted in no overheating, or perceptible warming of the inverter or battery. I used a 1.5AH Dewalt battery pack. The battery pack showed a .5 volt drop after 10 minutes. Cons: I couldn't find if this inverter outputs a pure sine wave, or a modified square wave, so I don't know if it's okay for electronics sensitive to waveform. Notes: The instructions say the inverter has a soft start feature that starts at 110 volts, and climbs to 120 volts. I noticed 109.8v to 110.5v, but no further climb during the 10 minute test. I don't consider that a con. 110v is fine for my use. When choosing a product, it was a toss-up between an inverter with a battery adapter, or an inverter with internal battery pack. During my reading of info, and reviews of other products, a common theme I noticed with inverters with battery adapters was output at only 85v +/- volts. A common complaint with internal battery pack inverters was battery quality, overheating, and failure. Quite a few inverters (with internal batteries) would not take a charge after a few months. That could be faulty design, or low quality batteries. In summary, I would buy again.

Works great for it's intent... Light is great for indoors or low light area.. definitely not a spot light light and easy to use you'll be happy you bought it. Very handy to have around and doesn't take up much room. I use it in my rv

Me proivieron mi opinión producto malo! Por decir algo

Camping

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.
