    I bought it because it was on sale $10.99 and it was old and outdated for backups batteries, no C outlets only use A, took more than 4 to fully charged and it was last after couple changes.You get what you pay for.

      Hi Hongtri2523,
      We appreciate your honest feedback. This model is designed as a basic backup option, so charging speed and port selection are limited compared to newer models. If you need faster charging and USB-C outputs, we recommend considering our latest series for better performance.

    A great backup power source. Has a monitor showing the percentage the backup is charged. Important for an alternative power source when you can’t be plugged in to a wall outlet.

    Portable charger works as intended. I like how it can be charged with a type c cable. It does take a while to charge so pick the right power source.

    Although it takes quite a while to recharge, it repowers my Samsung S22FE from near 0% to 100% in less than an hour. I can get two full charges before it runs dry.
