    Must have this powerbank for every trip. I have been using it for every single trip and it gives me multiple charges for a whole day worth continuous use.

    It's heavy, but it lasts forever, use it while recording games on an ipad and after 90 minutes it's still above 90% charge.

    It lasts long & charges my phone several times before needing recharged. However its ridiculous how long it takes to charge it. I have a 100 watt type c charger & it takes 6 hours to charge on it.

    Solid power bank. Tons of capacity to keep devices charged on the go. However, it wouldn’t charge my M1 MacBook Air. Not sure if it’s a problem with the laptop or a limitation from the power bank.

    At my work, we can only use battery fans at our desks. It gets really hot in the lobby area where I work, so the fan is on most of the time. My fan charges by USB cord which needs to be plugged in occasionally so someone suggested I buy a power bank. I bought this one at Best Buy and it keeps my fan running all day . I take it home at night to recharge and then it is ready to charge my fan the next day.
