Rolling Square’s Supertiny claims the title of world’s smallest 100W USB-C charger.

The company has launched a Kickstarter for a new version of its Supertiny charger that bumps the output from 65W to 100W with a minimal size increase. The new 100W Supertiny GaN Charger weighs 100 grams (20 grams lighter than Anker’s smallest) and is available for preorder for around $53 with shipping expected in July.

<em>Even with GaN technology the compact charger will get hot when used to charge “energy-intensive devices.” Rolling Square has included a ribbed design on the outside of the charger to help reduce physical contact when unplugging it.</em>
<em>At just over two-inches long and 1.38-inches on each side, the 100W Supertiny charger is comparable in size to the AirPods’ charging case.</em>
