    Customers are mixed about the charging of the power bank. Some mention that it charges at an expected rate, is able to fast charge 2 devices at once, and is very easy to recharge. However, others say that it gets very hot very fast, it might not charge fully, and that it loses that charge entirely in a week or less of sitting.

    Light weight, low profile. Excellent for pockets, recharging devices.
    Very slim profile and lightweight, this battery is perfect for an unobtrusive backup for a phone on a night out. It is also very handy for powering LED holiday lights on my musical instruments. I can attach the battery on the back of my instruments with poster tack and the slim profile allows me to keep the battery on the instruments in their cases. Enough charge to run for 6-9 hrs of shows before recharging. Highly recommend this product.

    Reviewed in the United States on July 5, 2023
    Charged my Google Pixel 4a from 10% to 99% in one hour, using up most of the juice in the battery bank.

    However, it takes many hours to charge up the battery bank and it loses that charge entirely in a week or less of sitting unused. Poor battery life. If I expect to need to use the battery bank I need to fully charge it the day or night before. This will not work for long backpacking trips like I'd hoped. 🫤

    VERY lightweight and small.

    The C port is bidirectional - both input and output.
