Dual USB charger for Fieldpiece leak-detector

The Kastar LTD2 is a compact lithium-ion charger that accepts two Fieldpiece RLB2 packs at once. It draws 5 V at up to 3 A through either Micro-USB or USB-C and delivers 4.2 V at 800 mA per bay. An LCD panel shows the charge state of each cell.

Ideal for HVAC technicians who run two detectors

Suits professionals who need both detectors ready for a full shift without swapping packs. Not suited for users who rely on a single battery or who require a charger that operates from mains AC without an external USB power source.

Steady output during extended charging sessions

Each bay maintains a constant 800 mA current until the pack reaches 4.2 V, so the second detector battery finishes at the same rate as the first. The 15 W input ceiling prevents the charger from slowing down when both slots are occupied.

Questions about this item

What USB power source do I need to run the 15 W charger?

Use any 5 V source that can deliver 2–3 A — a typical phone charger, power bank or laptop port — through the Micro-USB or Type-C input.

Will the LCD show the status of each RLB2 battery independently when two are inserted?

Yes, the intelligent LCD displays charging progress and capacity for both slots simultaneously.

How do I confirm the charger is delivering the correct 4.2 V 800 mA output after setup?

Watch the LCD — it shows real-time voltage and current for each bay so you can verify the 4.2 V 800 mA charge rate.
