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

I bought this specifically for Jamaica. This needed urgently because of lack of electricity caused by the hurricane. It works well and I plan to buy more in the near future Read more

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. Read more

If you have a get-home or bug-out bag, these are essential. I had a single battery one that used magnets to hold it, and it was only good for charging a dead phone to about 5%, but the battery got *HOT*.... it made me very nervous. This thing is perfect for an "emergency" and it doesn't rely on shorting out the battery and getting hot. Yes it has a light which is OK, but if you're like me and getting this for an emergency backup, you already have a light. Read more

I would not suggest this as a main charger since it's slow, but in an emergency situation, it will keep your phone charged. The small LED light is an added bonus when trying to navigate in pitch black. Read more

These were great, they work on iphone and android. Did not think there would be a use for this and we went camping! Folks need to get flashlights! Charges up plenty to use phone liberally. Read more

Does not work as well as expected or as well as you are led to believe, works for very small power devices. Read more

This is the worst charger I have ever had. Instead of charging it up, it went backwards. I started at 49%, and 2 hours later it was at 48%. So I had two other people try it out, thinking maybe I did something wrong. It did the same thing for them. Instead of charging it up, it charged it down. The only thing good on it is the flashlight. Don't waste your money. Read more

I wanted to get something that could charge my devices in case I lose power, and I found this item. It's small, compact, and easy to carry around. It is nice to know that I can still power my phone and tablet. Read more
