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.

Works really well

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.

Works as advertised.

Very handy.

I was very excited about this item, but when I put the AA alkaline batteries in, nothing happened. I have read review that said only the flashlight works but my flashlight will not even turn on. I am very dissapointed.

Update: Ultra Alkaline batteries work best. Can get a couple hours of charge off 4 batteries. Maybe more if you’re not on your phone at the same time. If you’re going to buy this make sure you have plenty of alkaline batteries. Otherwise, you will be frustrated. May need hundreds of batteries if in a storm or power outage. My point is that this does work but don’t expect to use this full charge or to be able to binge watch any movies or shows. For the price it serves its purpose.
