    This portable charger is a great high speed charger, allowing two usb-c devices to recharge simultaneously. The led numerical status is very useful to indicate approximate time to fully charge the device(s), or the time to recharge the charger itself.

    I bought this for my new job because I don't have wall power access during the day. One charge keeps my iphone 12 mini topped off all week. The glue holding the magnet to the usb c charger is weak and the magnet came off. This doesn't effect permormance of the product just the little loop does't click into place. Using my rewards I got this battery for $5. So at that price it was a steal.
