Kuxiu is back with a new S3 portable battery that addresses most of the issues I had during my review of the S2, aka the “world’s first” semi-solid state power bank. It also introduces a few new ones, while adding useful features like a kickstand and integrated USB-C cable.
As a reminder, these are not true “solid state power banks” despite the marketing hype. The 10,000mAh Kuxiu S3 uses the same solid-liquid mixed electrolyte found in the S2, making it less prone to thermal runaway…
