    A bit on the heavy side, but justified by it’s large capacity, charges iPhone 17 up to 3 times per charge.

      Hi tsb3
      Thanks for the great feedback! We're glad the MAX 20,000mAh power bank is delivering solid performance for your iPhone 17. While it’s a bit heavier, that extra weight comes with serious charging power — like carrying a backup outlet in your bag. We’re happy it’s meeting your expectations!

    It provides a lot of battery but it takes a while to charge it 100%. It is a little bit heavy in my opinion

    I was in need of a power bank because I was on day 2 of no power and had no clue when I would get it back. This was already charged so I was able to immediatly plug in my phone to get it charged. Getting it recharged took some trial and error but I eventually figured it out.

      We're so glad to hear our power bank was there for you when you needed it most! We apologize that recharging it took some trial and error, and we appreciate you sharing that feedback. For future reference, the power bank is recharged via the USB-C port. For the fastest recharge, we recommend using a wall adapter that supports Power Delivery or Quick Charge 3.0.

    Got this for like $15. Bought to use with my Quest 3 and it does the job. Can play for much longer periods of time It has a large capacity, so it takes a long time to fully charge, but definitely worth it.
