Battery Operated Phone Charger Emergency|USB Battery Powered Power Bank Portable 4 AA Batteries Powered Outlet (Black)

I just got it. It seems to be working. Funny I couldn't find this anywhere in stores but if you have a real power outage, a pack of AA batteries can now keep your cell phone going. And there's an LED build in for light if you need it, which is always nice.

UPDATE: Tested with alkaline batteries. After three hours, my 10k mAh power bank was still at 25% charge, and now the light doesn't work. Will be returning this, regretfully.There's a lot to like about this item. It's compact, with an easy-open top. The LED light is bright and steady. And the price is right. That said, it does seem to be a little slow.I tested it with the only two types of batteries I had on hand, a set of Super Heavy Duty ones from a dollar store, and a national brand rechargeable type. Alkaline batteries are strongly recommended by the manufacturer, and I don't doubt they'd yield better results than what I used. But here's what I found:After one hour, the Super Heavy Duty batteries had charged my older Android from 82% to 88%. After an additional hour, it was still there. Thinking the batteries may have died, I pulled and tested them. They were just about 35% depleted.The second test, with branded rechargeables, yielded similar results. After one hour, it charged to 95% from 88%, and wouldn't go any further. Those batteries tested out at around 30% depleted.Things I think would help yield better results: A faster cable, the proper type of battery, and charging a power bank instead of directly charging a phone. I have a few 10-20k mAh banks I'm going to fool with to see if I get better results.The bottom line? It does the job, albeit slowly, and would probably charge a small flip phone more quickly. With a good supply of AA alkalines, it's a good alternative to solar for an emergency tool kit, and worth the $7 I paid. I would buy it again.

I use these for LED signs! They’re nice because I don’t have to plug them into a wall and they run them all night.

Pretty good for the cost. It charges slow, but after 3 days without power, this definitely would have been handy to have to keep my phone charged. It's definitely worth having as a backup source.

Works really well

The flashlight like works but it doesn’t charge.

Do not buy not don’t waste your money. Do work/ don’t work/ do work/ don’t work/It no GOOD

Works as advertised.
