بطارية محمولة HyperJuice® Flex 10K Mini 30W

The 30W USB-C port actually fast-charges my phone instead of trickling like my old brick, and the whole thing still slips into my jacket pocket. It's roughly the size of a deck of cards, which is way smaller than I expected for 10K.

Took this on a weekend trip and it charged my phone from dead to full twice before needing a recharge itself. The 30W USB-C port is genuinely fast, noticeably quicker than the old brick I was using.

Slips into my back pocket without a bulge, which is more than I can say for my old brick. The 30W USB-C topped my phone up from dead in a little over an hour during lunch.
