Many appreciate its multiple ports and consider it a good value for the price. However, some customers find the device to be bulky and heavy.

    It can charge my phone and my family's phones very fast. It is great when you have a purse or bookbag with you to keep it in, it is a little heavy. Overall its a really useful and convenient product for the price I bought it at.

    Absolute life-saver! It takes awhile to charge up once you’ve drained the battery but is able to charge my iPhone several times over on one charge. The extra ports are super handy for multiple items as well

    I bought this to power my phone (gps mirrors from phone so it has to be unlocked the entire time in usage) and my helmet cam/Bluetooth headset (iPhone 12 pro max and Sena 50c) all day while riding my motorcycle. Works great! Just large enough to keep both powered all day (100% down to 20% after 14 hours of ride time). It does take along time to charge so be sure to give it enough time to charge up. You have to turn it on by pressing the button on the side. Otherwise it will not charge just by plugging things into it.plan on 6-8 hours of charge time to get it full from 20%. Good product, works great, lives in my back pack while I ride.

    It is big, so not for the light of heart. it does well-charging devices. all of my devices are large. I have an iPad pro 13in, Samsung s24 ultra, 22 ultra. i have fully charged two devices for a test from 15% and had more than half juice. the only downside is that it stopped working less than a year after purchase. It has been a few months and no reply from a warranty claim. the reason for 2*

    Only thing you’ll have to worry about is the size of it, last thru multiple charge cycles (3+) on my iphone 14 pro max. Has about two and a half charge cycles for an ipad.

    Holds a lot of power and charges in a reasonable amount of time, considering it is a powerbank. I would like to see it have a faster charging capability, but I still love it. I definitely recommend the c to c charging lort to get your fasting charging capability!

    Bit more oomh than the 20k. Can charge phone, tablet, and computer - if all dead at once (tested) except gaming laptop, she gets to 50%. 10/10 experience and the 20k I bought before worked for years before showing any signs of decay. Great product through and through. (Maybe im bias because I have "battery range" issues) But this has got me feeling comfortable.

    Has amazing battery life, a full charge will last you weeks if used lightly. Overall great portable charger for all devices, only complaint is you can’t use a usb-c to charge your phone or device so no fast charge sadly only usb.
