Deity DQC2 Two-Bay Smart Battery Charger

The DQC2 charges two 2054-style eSmart packs at once, including the Deity S-95, and takes power from two USB-C ports rated at up to 100 W each. Running it from one port works and simply charges more slowly, which matters on a job where the only spare supply is a laptop brick. Any 2054 smart battery that speaks the SMBus v1.1 interface will charge in it, not just Deity's own.

An aluminium alloy body and a fan handle the heat of fast charging, and an LED meter shows progress per bay. Up to three units daisy-chain together for a cart or a charging shelf that has to turn over a day's worth of packs overnight.
