Portable Charger Power Bank 16800mAh Ultra Capacity Backup Battery with Digital Display LCD Screen,Dual Outputs External Battery Pack High-Speed Charging for Smartphone, Android Phone,Tablet & More

I spend a lot of the day away from a charger source so decided to pick up a power bank. I love the digital gauge on this showing the remaining charge and that it can you can fast charge the bank itself when it gets low and the bank will also fast charge a device at 2.1a. Very happy so far.

I've purchased 4 different kinds of portable power bank from Amazon, this one is by far my favorite. What I like about this product:* Light weight - this one is compact and light compared with other power banks of similar capacity* LCD display - the display makes it easy to know how much power is left and how far (while charging) it is from fully charged* Charging speed - it took about 28 min to charge my iPhone 7 plus from 17% to 90%* Large capacity - I was able to charge my phone 4 times (all from < 20% to ~90%) and it still had 20% power left* Quality built - the power bank stays cool while charging (no concerns on overheating). I once dropped it on the ground by accident, the case stays intact and there seems no impact on charging capability.

Reviews looked great on this charger, unfortunately mine lasted about a week with good charges and after that the display stayed stuck at “99” but was never actually 99% charged. So I continued to try and charge my phone with it and my phone wouldn’t even pick up that it was connected to anything. The charger would then just completely die. Super disappointed in this purchase. Would not recommend.

I bought this battery pack for a recent 2-week bicycling tour of Albania, Montenegro and Croatia - I needed something with minimum of two USB inputs as I had multiple devices to keep charged, something small enough to fit in an easily-accessible bicycle pouch on top of my frame, that would be able to charge my phone multiple times (as I was using it full-time as a navigation device), and have juice left to charge my two USB bicycle lights... I just got back yesterday, and this battery pack was easily a gear MVP of my trip!! Can't recommend it enough.Anytime my iPhone 8 went below 70% battery life, I plugged it in - I had my phone plugged in most of the day (I was doing 4-8 hour rides a day) and this battery pack itself never dipped below 40%. The dual USB inputs meant I could keep my phone charging, and easily plug in a second device - often I would charge my GoPro or one of my bicycle lights during lunch.As far as features, the light-up LED battery indicator number was actually really handy to know exactly where the pack was at for life. And the size is perfect, in terms of dimensions - basically like a (really) thick wallet. Definitely very dense within that size, though - it's pretty heavy, but absolutely worth it for the incredibly long battery life as long as you're not ultra-light backpacking or something. Charging devices wasn't incredibly speedy, and the recharge time on the pack itself definitely took a few hours (I would just recharge it every night), but the sheer volume of power in this thing made it all so worth it. I'll be traveling with this thing on many of my upcoming adventures. Highly recommend!!

I should have listened to the bad reviews. Exactly what the others said. Charged it up and never worked again. Sure the screen lights up "100" but it never charged any device. iPhones, variety of Samsung phones, bluetooth speaker. NOTHING CHARGED.

This product does not work on Samsung S7. Bought for Disney for one purpose! To charge my phone & it failed to do so with several different usb cords including my charger cord. Very upset to buy a premium priced charger & it not work. Ruined my trip because my phone died halfway in the park.

***Update 3/25/2020*** product stopped working, as all other 1 star reviews are saying, the item gets stuck on a certain charge number on the LED display and just stops working. Dissapointed, updating my review to 1 star, probably recharged my devices about 20 times before this started happening.

I used it while on vacation in Florida with my family and on the morning that we were leaving, I connected my phone only for it to not turn on. I removed my USB cord from the power bank and pressed the power button to see how much life was left (18). It remained on display and would not turn off. I thought that maybe connecting the power bank to its charger and charging it would correct the display issue but it has remained on the "ON" position, stuck at 18, for over a day now. Unfortunately, the time to return it passed 3 months ago so I've just lost money on a product that I didn't get to use for a full year.Original Review: I absolutely love this Power Bank! It came in handy while having a 7 hour layover in Amsterdam: TWICE! It charges extremely fast for both my iPhone and Samsung; my tablet too. It has two USB ports to allow charging two devices as once and there's a digital counter that displays how much energy is left for charges. Recharging it is fast as well. I will definitely buy a second one.
