Best portable charger to own

Got this charger because I really need a portable for my work device as the phones Walmart gives employees don't last the whole day without a charge. They give us a google pixel 8a device for working purposes but they get to 30 percent before we even go to lunch, 4 hours and a half into our 8 hour shift. During that one hour lunch period I plug my work device into this portable and it goes from 33% to a whopping 90%. I'm impressed at how fast this portable can charge a device. This is a really good portable charger to have, don't miss out and get it. It charges phones at a really fast speed and it even charges them more than once. I even use it to charge my iPhone 17 pro max and it also charges that phone at a really fast speed. It packs a lot of power to charge devices multiple times before it itself needs to charge. Definitely would recommend this product to everyone.

If you don't have a newer iPhone (15 to 17, I think; it didn't fit my 14), you have to buy an extra cord, but it was ony $6 at Walmart, which was a little hassle figuring that out for me. The power bank is larger than my last one, but it still fits in my purse and tells you how much charge is remaining, so I like it.

Powerful and compact power bank, well worth it!

This is a great power bank. Provides a lot of power, nice and compact. It also has a built in C charger cable. The digital screen is helpful for knowing how much charging power is remaining. It recharges quickly and provides plenty of power for multiple devices.
