    Best charger I have ever purchased. Especially since now every device I own including vape device is USB C . Charged all my devices fast & still have nice amount of juice left to charge again if needed. And no not receiving anything for this review

    Totally saved me when traveling recently in EU/UK and was out all day using Maps to get around, which drained my phone battery usually by noon. Could charge phone a little bit faster, but I never had to worry about needing to recharge.

    Great portable, powerful powerbank, no USB-C In

    It’s a great high-power, portable power bank that charges your device with ease! Gonna have to remove a star because it doesn’t have a USB-C Output port, only a USB-C Input for charging the power bank, which is a huge bummer considering how many devices are powered by USB-C nowadays. Other than that, it’s still an excellent option!

    This portable charger is amazing! It has saved me a few times already when I forgot to charge my phone during the night and need it the next day out of the house. The charger has a nice case that fits in my purse. It’s not heavy or too big.

    Purchased this to use with an iPhone 8. It worked great and the phone charged quickly. Got a couple of days of charges before the battery needed recharging. The recharge is slow, so I just charge it over night.
