Coast ZX20B Rechargeable Booster Pack for RL20R

The Coast ZX20B is a rechargeable booster battery, designed to extend the use of the RL20RB or RL20R by charging the built in zithion-ion batteries with an array of other useful features.

The ZX20B is a multifunctional tool, not only does it recharge the headlamps but it also acts as a rear-facing independently controlled red safety light which features two modes, solid red or flashing red. When turned off the safety light doubles as a reflector, ensuring your safety at all times. The ZX20B also features a COB light which has an output of 200 lumens with a 10 hour run time, perfect for if you need a second light source.

The ZX20B simply slides and snaps into place over the top of the built-in battery packs and begins charging the headtorch, increasing its runtime. To operate the rear red light press the power button on the back of the booster battery. Press again to cycle through the red flashing and red constant modes with the final press turning the light off. To operate the COB light press the power button on the side of the booster battery with each press cycling between the high and then the low outputs with the final press turning the light off. 

The ZX20B has a built-in rechargeable lithium-ion battery and comes supplied with a USB-C cable for charging. Remove the dust cover from the charging port on the side of the booster battery and plug in the USB-C cable. The charging indicator by the charging port shows the level of charge left in the battery.
