Nitecore Carbo 20 20,000mAh 65W Waterproof USB-C Power Bank

Compact & Powerful This is a great travel charger - small, not heavy, feels very solid and high-quality, which it should, at the better part of $200. It's going to be at the center of my travel plans this summer.

Excellent power bank. Not that big to carry around yet powerful enough to handle the job. I like you can charge two items at the same time.

IPX8 All the things!

I have the Carbo 10 and now the Carbo 20. After having a Dark Energy Poseidon Pro blow up to double size right at 2 years, I won't be going with them again. I haven't submerged these yet, but the 10 has been in a Florida thunderstorm without any ill effects. Now make a Carbo 40 please.
