    No gimmicky led screen, small and compact enough for its capacity. The led indicator could get an brightness upgrade. Hard to see under bright light conditions.

    A little overpriced in my honest opinion. Simply because this device still only charges output with a USB-A end and in today's age, you can easily find a USB-C output charger that will no doubt charge 3x as fast with half the cost of this portable charger. I found a different charger that did just that a month after buying this and have not even gone back to this charger since. In terms of the device, at 100% power, it gave me about 5 full charges on my iPhone 13 Pro Max at the time. But i do remember it took about an hour for it to just fully recharge itself when plugged in.

    Bought for my sister; she says she would give it ten stars and that it is the “Mercedes” of chargers. I am thankful she will now have something that is fast and reliable in an emergency.

    Great backup power unit. Charges up pretty slow, we find that if we use my wife’s usb-c 65 watt charger, that helps a lot! But it does what it advertises, we use it daily since we are always forgetting to charge our devices lol.

    Provides me enough juice to charge all [iphone+headphones+Airpods+macbook air] devices during my 12-14 hrs travel every few weeks. The carrying bag could have been a little better with may be a fabric design and a pocket for the charging cable.

    Thus far pleased with this Powerstation. Mike husband was pleased with this as one of his Christmas gifts! It charged up relatively quickly. Fortunately, we have not yet had to use due to power outage, however we could have used it last month!

    This product does an excellent job in keeping your phone charged multiple times. It takes a little while to get it back to full, but seems to fully charge your phone at least twice. It's a little bulky and heavy, but otherwise a great value.

    Lot of battery power, good value. you know you'll have enough power for few devices. Is as heavy as like holding 3 phones. Totally recommend if you want to have a backup in backpack.
