Replacement battery and charger kit

This kit includes one Kastar BL-5B lithium-ion battery and a matching smart LCD charger. It is designed for owners of compatible Blaupunkt, Callstel, Prestigio and ECHO devices who need a spare or replacement power source. The battery delivers a capacity of 890mAh at 3.7V, providing 4.26 Wh of energy. The charger accepts AC 100-240V input for worldwide use.

Charger behaviour during extended use

The charger supplies a steady DC output of 4.2V at 600mA and uses LED indicators to show status: red while charging and green when the battery reaches full charge or stands by. Its foldable flat plug allows the unit to sit flush against a wall outlet, reducing strain on the socket during long charging sessions. The wide input range of 50 to 60 Hz ensures stable operation on different mains supplies.

Compatibility check before ordering

Verify that your device uses a battery with part number TM533443 1S1P or one of the listed model numbers such as Blaupunkt BT Drive Free 111, 112, 211 or 311, Callstel BFX-300, Prestigio RoadRunner 505 or ECHO HD eR1. This pack contains a single battery and charger; buyers needing multiple spares for a fleet or for continuous rotation should plan accordingly.

Questions about this item

How much heat does the 4.2 V 600 mA charger produce when left plugged in all day?

The charger draws only 600 mA at 4.2 V, so it stays cool to the touch even after continuous use.

Which devices must I already own for this BL-5B pack to work?

It replaces BLAUPUNKT TM533443 1S1P or Callstel TM533443 1S1P batteries in ECHO HD eR1, BT Drive Free 111, 112, 211, 311, Callstel BFX-300 or Prestigio RoadRunner 505.

Will the foldable-plug charger still fit older UK sockets used with my Prestigio unit?

The foldable flat pins are designed for standard AC 100-240 V outlets; they insert and fold without blocking adjacent sockets.
