Gens ace iMars Mini G-Tech 2-4S 60W Smart Charger

The Gens ace iMars Mini is a compact 60 W balance charger for 2-4S packs, powered from USB-C, for charging small-quad, RC car and plane packs at the field. With a Gens ace G-Tech smart battery connected it reads the pack type and voltage through the smart balance connector and starts at the recommended current after 5 seconds; other packs charge once you select the chemistry and mode by hand.

Feed it from a USB-C PD adapter or power bank that can deliver 20 V at 3 A to reach the full 60 W — a 5 V/2.4 A source caps input at 12 W, and no power adapter is included. At 60 W a 4S pack charges at up to about 3.5 A, roughly 2C on a 1500 mAh pack, so it is best matched to 2-4S packs up to a few thousand mAh.
