Yes, It works!

These hold a lot of power. They turn off after your phone is fully charged. I noticed another reviewer was looking for one that will trickle upon full charge. This one turns off, but I like this logic because it preserves they charger's battery not that it really needs it. I hooked it to a 2 amp charger when I opened the box and it went from 14% to 100% in about 6 hours. If I had used a 1 amp charger that time would double. I've been using the one I have all morning and on a dash cam, and my iphone and it's only down to 95% now. I charged the dashcam all the way up and the phone is up to 94% from 57% while I am using the find friends feature which uses quite a bit of power relatively speaking. So I appreciated the fact of how much crazy mad power these little critters actually hold so much, that I ordered a second one. This is a whole lotta Lithium for 19 bucks. I might buy a third if I find a use. I think two should be sufficient and will double the effective charging life span since with two, one will get a break while I'm discharging the other one. That way I won't have to ever wait on it to charge either. I don't think they're kidding about the full price of this. It's a no frills gulf of power for 19 dollars if you need a good charger. This sale won't last long. Hurry while they last! Not available in stores! Void where prohibited. Restrictions may apply. This is not a drill.

This is my second time buying this device.Pros: I absolutely love the small size. It feels sold and heavy in hand. Assembled strong. It charges my Samsung s8 efficiently/ fast. I think it takes like 5 hours to charge from low battery but idk. It'll last you well over 24hrs. which is wonderful. Bang for your buck. Best part of the device.CONS: BUT it is defective. Only one output works. The other does not stay on for longer than 30 seconds even if you use the power button to manually turn it on. And I find this super annoy because I want it to work the way it's supposed to as they claim. What's the point of having 2 outputs if one is completely useless?!So I ended up reutning it and got another one. Turned out defective too. I'm keeping it tho. Although imperfect, the charge hold is long lasting. So it serves its purpose.Worth buy? Yes, I think so.

Most important thing is the size of this thing. I waited a month to review this. This battery fits in the palm in your hand it’s about as heavy as my iPhoneX. The initial charge took a few hours but I have charged it about three or four times and after a full charge the refuel doesn’t take too long. I carry a small crossbody and this fits perfectly without being in the way. I’m currently on vacation and I have just had my phone plugged into this thing the entire time without any battery issues. I also really love the on and off button with a number indicator of the battery life remaining. My only grip is that the charging cord that came with it does not charge the thing. I’ve been using a totally different USB cord I had laying around. But I really think it is a great deal and a superbly made product. You definitely do not have to be gentle with it. And I left out that you can charge two devices at once with this if needed! Hands down recommend

This works really great, until it doesn’t. What I mean is it held it’s battery life for about 3 1/2 days. End of day 1 the battery said 92% remaining, end of day 2 it was at 84%, end of day 3 it was at 69%. On day 4 I figured it was good at least for that day. It lasted about 5 minutes charging my phone & was dead. That was a big bummer considering I was sightseeing in Spain & couldn’t easily charge my phone while out & about. Lesson learned & I charged every 3 days without issue.

I charged it to 100%and put it in my purse. A few days later, it was still 100%. I was down to 20% on my phone, the battery pack had my phone up to 100% only using 20% of it's charge. I didn't like the fact that it sat in my purse a few days after I used it that one time, and it drained back down to 0%.🤔🤷‍♀️ That, and there wasn't really any instructions, so it took trial and error to discover that if you're charging only one thing at a time, even tho there are two ports to choose from, only one continues to charge after a few minutes, and one does not. Maybe mine has a defective port? Like I said, didn't get any paperwork, so.....?

This has very mixed reviews and I was leary about purchasing. I bought this for overnight backpacking trips where every single ounce counts. It has performed just fine so far and it has functioned even as high as 13,000 feet and in the snow without any problems. It does take a long, long time to charge the first time, but big deal. For the weight and the price, its perfect.

This charger was awesome until it randomly decided it wasn’t going to work anymore. I was out of the return window, but luckily I was able to return it anyway. I’d buy again if I felt like I really needed another.
