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.

Great Power and Super Convenient

One of the best portable chargers I've owned. The size is compact and easy to carry, but it still has plenty of power. It charges my phone quickly, and the built-in cable makes it really convenient, no need to carry extras. We've even used it for our VR headset without any issues. I like it so much that this is my second one. Great value and very reliable….highly recommend!
