Power Bank 50000mAh Portable Charger: 22.5 W Fast Charging External Battery - Powerbank with Flashlight and Large Capacity-Black 2.5×20000 mAh

Superb. Just make sure you have a powerful quick charger, otherwise it will take a very long time to recharge.

Disappointing overall. The inclusion of a Lightning port feels unnecessary and outdated, as Lightning-to-Lightning cables are rarely used and primarily apply to older-generation iphones or Apple accessories. Having only a single USB-C port alongside a Micro-USB port, which is typically reserved for device-side connections, makes the setup feel poorly considered. The port selection seems out of step with current consumer needs. A simpler, more practical configuration using USB-C and USB-A would have been far more appropriate.

This is the size of a housebrick, and probably heavier!

Ok

This is a very good item but it is way too big for what I needed for traveling
