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

These work if your in a jam. When our power went out from the snow storm these literally saved our household. Lol. I have a toddler who loves playing and watching videos on her tablet. Well without power it wasn't possible so these charges came in handy to have. It literally saved the day and made a toddler very happy. So yes they do work and are small enough to carry anywhere. I bought 2 and wil definitely be getting a few more. It's very easy to use. Just put the lithium batteries in and go. It also has a flash light and it's bright. :)

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.

Life Saver for re-charging cell phones during 8 day power Outage - Easy to Use - Well Made - Completely portable - Uses AA Batteries - Has Flashlight Feature - Functions Very Well

Strictly for emergency charging...or have several extra batteries handy. 4 new batteries will not last to make a full charge!! But, size and portability is great! Seems to work pretty good...but, AGAIN, not intended for primary charging !!

Novel design, good price, and surprised we haven't seen these sooner. Made it part of my camping and power outage kits so i can use the AA batteries in them as an additional backup. Flashlight is not very good but it's adequate enough and given that it's part of a kit that already has a separate flashlight, I am not overly concerned with it. Think of it as good enough to find a better flashlight in your house to use it.

Simple and easy to open. Takes typical batteries and works just as described.

For mine to work I had to turn off the phone to recharge. Slow recharge. Did not charge my Motorola 5G 5 when it was turned on.

There was at least one review that said this doesn't work and I wish I listened to them. My lights recently went out for 8-12 hours and I bought this when they were out thinking it could be a while before they came back on. It has a flash light and that works great. For some reason though, it has a red backup light on at all times when not in use, which means it's draining the batteries when it's not being used. I was really hoping the review was wrong, but they so got it right. Save your money look for a better product.

Llego antes de tiempo pero no funciona

It will do for an emergency but it takes an absolute age to recharge a phone

This works.. This is a great product to have in an emergency, if you are out in the wilderness and both your mobile phone and your rechargeable Battery Bank have no power left.. Just pop in 4 AA batteries and charge your mobile phone, easy.. The result I got with my IPhone 16 (which uses a USB A to Lightning connector), using 4 new Duracell Plus batteries in this Battery Operated Phone Charger, my IPhone was charged to 56% from 4% in 5 hours.. It gets you out of trouble, this can be a life saver.. And they are so affordable.. Just keep plenty of AA batteries with you.. Amazon have these batteries with a 10yr shelf life, a great compliment to a life saving situation..

Pratique quand on a pas de prise de courant dans les environs... À acheter d'urgence. Et c'est pas moi, le vendeur.

Didn’t charge my phone at all. Rubbish
