What the charger does and who uses it

The Kastar LTD2 is a dual-bay USB charger for Canon BP-511, BP-511A and related lithium-ion packs. It powers two batteries simultaneously from any 5 V 2-3 A USB source. Photographers with multiple Canon EOS or PowerShot bodies can keep spares ready without a mains adapter.

Thermals noise and power draw

The unit draws up to 15 W from the USB port and delivers 4.2 V at 800 mA per bay. No fan is fitted, so operation is silent. Heat output stays low during normal charging cycles, making it safe to leave on a desk or in a bag while batteries replenish.

Build connectors and daily use

A compact 5 by 3 by 1 inch chassis houses interchangeable plates for the supported battery types. Both Micro-USB and USB-C inputs are provided, and a Micro-USB cable is included. An LCD panel shows real-time capacity and charging status for each bay, letting you confirm progress at a glance.

Questions about this item

How do I install the BP-511 battery in the Kastar LTD2 and what step do people miss?

Slide the battery onto the interchangeable plate until the contacts click, then connect the Micro-USB or Type-C cable to a 5 V 2–3 A source; the step often missed is confirming the LCD shows both slots active before walking away.

What maintenance will the charger need later?

Keep the contact pins clean with a dry brush and replace the Micro-USB cable if the plug loosens; the unit itself has no user-serviceable parts and the LCD backlight is not replaceable.

What limit appears first during sustained charging of two BP-511 packs?

The 800 mA per slot output caps the charge rate, so two depleted packs draw the full 15 W input continuously and the charger’s thermal protection will throttle current before the batteries reach 4.2 V.
