    This battery bank works very well with my phone. It fully charges my pixel 6 pro from dead almost 4 times. I also use it with my quest 3 and I dont have to worry about how long i have left to play. Over all no complaints and would buy again.

    I bought this for travel to India. It passed in carry on luggage. Beware not to pack in check-in luggage, as it is not allowed. The pack is pretty heavy but light enough to pack in backpack. It charges my Samsung Galaxy S20 and son's Galaxy S22 as a fast speed, not superfast speed, but that is acceptable to me. Ensure you have the right cable. It would not charge my tablet (micro-usb) with certain cables. Could not get the trickle charging to work.

    I use this on the regular and it works so well. Charges my phone multiple times after only charging it once. It's pretty lightweight for the power that it has and the cord that it comes with is just so convenient to keep in the little bag
