    Works perfectly! It came in handy because the person I bought it for had no battery when they opened this gift and they were able to charge it right away.

    It is a very good battery. It is very thin which makes is easy to fit in your pocket and you can barely feel it on the back of your phone.

    These are great.. They are small enough to fit anywhere that they do not fill my bag. Yet they are powerful enough to charge both my Android and my iPhone, I recommend them.

    This power bank is small and light so it doesn’t weigh me down. It’s magnetic wireless so I don’t need to carry a power cord. I would recommend it.

      Hi RobertoG,
      Glad the slim design works well for you. Fast‑charging performance can vary depending on the phone model and how well it supports the charging standard, so some devices may not reach the full advertised speed. Very sorry it didn’t meet your expectations on fast charging.

    Usb C charge works like an other, and has a good charge. Magnet Charge is pretty good for an emergency charge, especially if not using phone while charging. If im using my phone, magnet charge mostly just prevents battery from charging and makes everything hot. Recommend Magnet Charge while phone is off, and it works nicely.
