GRUCORE 18650 Battery Charger Slim 3A USB 2 Ports LCD Indicator Power kit, Black

This is literally a huge version of the power-bank that you use to charge your phone. I used to have a lot of problems when I have my outdoor cinema in my patio. There was no place to run a power cable from and if I needed to do it I need to leave my windows open and that was a lot of struggle to me. So, I ended up calculating the power necessity and buy this one. That was enough to supply a projection device, apple tv, and a sound bar for 2 hours movie long. My next plan is watching my movies at the camping with my beanbags.ps. Do not forget to calculate your power necessity before you buy the product. Obviously don’t expect to run a camping fridge for a week with something this size. But if this meets your need this one is very portable and practical device.

At first place, the generator did not work for me so I returned the item and later seller reached out to me and for customer satisfaction, he not only gaurnteed the quality but also arranged a replacement. The new unit is working great. I had to fully charge it and have it tested at home before going out for the camping. It's very portable easy to carry generator with a strong carrying handle on it. Can't really say how many hours it actually worked because I used USB based gadgets to recharge.

The product fails to charge. I have tried both a home outlet and the car charger. It will power something then disconnect after 20 seconds. I can’t charge this thing so once it runs out, it’ll be worthless. This is a junk product, will returned it today!

Looking for an item to work with my CPAP testing so far so good. it lasted two nights without the humidifier on. It wont make it through more the night with the humidifier on. Depending on how long you sleep it might not make it through one night with the humidifier on. I bought a DC plug to try it that way and seemed to not work but that might have been operator error so will be testing that part over the next few days. Looks like it is a good fit it is a cpap support item you are looking for. Like I said so far so good

Bought this to run my 12V DC car fridge as advertised but it can't start the fridge. The generator would trip immediately and and stop working all together. The only way to reset it is to plug it in a charger. The fridge is only pulling 4.8 A and the generator is rated at 6 A output. Got busy and didn't get around to exchange it and didn't realize the return / exchange period is only 30 days so now stuck with this junk.

Worked ok after the first charge and now it doesn't even fully charge. The meter only goes to 3 out of 5 lights and have left it charging for several days. I have a lower rated battery and works better than this one.

Purchased this power station for my 48W portable refrigerator. Unfortunately, even it's a 280W power station, the unit went into protection from time to time when the refrigerator started.The 250Wh capacity is about right. For the money I paid it's a good unit for my small amperage applications such as charging my phone and laptop. It could be charged by my 12V 100W solar panel; took about total 10 hours from ~20% to fully charged.

This thing is handy. I love its quiet and efficient. I have a solar panel to charge it and it works wonderful as well. Its great because it emits no sound and is very low mantainence. It is heavy but I could care less.
