USB-C PD Power Bank 27000mAh, iProPower Portable External Battery Pack Power Delivery Charger for MacBook Air/Pro Laptop Tablet iPhone Smartphone 99.9 Wh

It’s nice, plenty of power. Durable. Great for traveling. I just don’t like how after awhile it stops charging and you have to press the “check battery level” button on the top to reconnect devices. The only constant charging port is the USB-C for laptops.

As my Macbook Air original battery can't hold a charge any more, I have to use it for my work everyday,so a replacement battery is so important for me, finally, I choose this ipropower 27000mAh high capacity external power bank battery pack,unexpected,it didn't make me disappointed, work so great and charge my macbook so great, I can use it to charge most of my devices like phone,laptop,camera... very decent charging speed, also it is so convenient for my internation business trip as the 99Wh power without limits for the airplane, really useful product and highly recommend.

Rarely does this thing charge, and when it does, it's slow. Even my old Anker 2.4 is faster, compared to the newer Anker models, there is no contest.Battery life is good though as it doesn't charge anything, so the battery doesn't drain! : \

Very good product, I use it for my iPhone and iPad when I out of office for long time, it back up my cell phone and iPad power.

Worked for a year or so - would give me a pretty good part of a macbook pro charge on a plane or sitting outside. Now it will not charge any of my devices - I plug it in, it reports four solid blue dots as "fully charged", but will not charge any of my devices from any of the ports.

This power battery is amazing. It was a little bigger than I expected, but it charges both my laptops (one older MacAir and one new one) and my iPhone and iPad. And it works quickly and I’ve spent a couple hours using it as a power source. Couldn’t be happier.

Iwas looking for an uncomplicated, yet sufficiently powerful power bank to accompany me “on-the-road.”It hasn’t disappointed me. I’ve been able to remain connected, while away from outlets and during interstate travel.Good job!

The battery was great for the first year although during the pandemic it wasn’t used much. I started to use this more once I started working a few months ago. Now it won’t charge, without it being charged I can’t use it. It started dying out when I would plug tablet to charge. Now battery won’t charge at all.

Seems like a good power bank fir phones and tablets but will turn off and on every minutes after 5 minutes trying to charge a 16” MacBook Pro
