Many appreciate its USB-C compatibility and the overall quality of the product. Positive feedback frequently mentions the charger's ease of use and convenient portability for travel. While some users noted occasional heating issues or compatibility problems with certain devices, these concerns were less frequently reported than the positive aspects.

    Item works well and stays charged for days when not in use. There is one that stays charge for 96 hours I believe and I think it would be as great as this one

    It’s a little heavy, but for the power you’re getting from this thing, not bad overall. Definitely gets the job done. A bit pricey though, there are slightly cheaper alternatives.

    I bought this back in June- its now December- LOVED it, until this week. I plugged my phone into it yesterday and I got a notification from my phone saying its slow charging which is strange because it never had before. Now the power bank is completely dead and I've had it plugged in for 12 hours, even tried a different charger, nothing. has the one blue light blinking like its going to charge but just doesn't. Wish it would have lasted longer than 6 months

    pretty darn cool would give 4.5 stars if i could, the only thing costing a half point would be it would be perfect if it was a tiny bit smaller
