Ricoh DB-110 replacement kit

The Kastar Li-90B package supplies one 3.7 V 1300 mAh lithium-ion cell plus a dual-slot USB charger. It targets owners of Ricoh GR III, GR IIIx, WG-6, G900 and the full THETA 360° line who need a spare power source for extended shooting sessions.

Dual-bay charging under load

The charger accepts 5 V input up to 15 W through either Micro-USB or Type-C and delivers 4.2 V at 800 mA per bay when both slots are occupied. An integrated LCD shows real-time capacity percentage so you can monitor progress during continuous top-ups without guessing.

Compact charger with swappable plates

The unit measures 5 by 3 by 2 inches and weighs little enough for a camera bag pocket. Interchangeable plates let the same dock serve other Kastar cells, while the included Micro-USB cable covers the most common power-bank and laptop ports for on-the-go replenishment.
