Work Through These Steps
- Charge both units fully before use, using the method for your model below.
- Try a different cable and a different USB adapter that meets the rating below. Some units charge only from their included adapter.
- Note how long the units run on a full charge and compare it with the table above.
- If the system has been stored, charge it at least every 3 months. Lithium batteries can stop taking a charge if left flat.
How To Charge Each Model
| Model | How to charge |
|---|---|
| C-5RC, B-5RC | Included micro-USB Y cable, or the charging case. The case needs a 5V / 1A (or higher) USB adapter and refills the units 2 to 3 times. About 2.5 hours to full. The units do not work while charging, and each case should only charge its own system. |
| B-8 | Dock the transmitter on the powered receiver, or charge it by USB-C from a 5V / 500 mA (or higher) adapter. |
| B-1 Lite, B-2 Plus | Included micro-USB Y cable. |
| B-3RC | USB-C, or the charging case. The case needs a 5V adapter rated above 2A and takes about 4 hours; the units take about 2.5 hours in the case. |
| B-6 | USB-C Y cable with a 5V / 1A (or higher) adapter, or the charging case. The units do not work while charging. |
| B-6 Pro | Transmitter: dock it on the powered receiver, or USB-C at 5V / 500 mA. Receiver: only the included DC 9V 1.2A adapter. Its USB-C port does not charge it. |
| B-7 Pro | Transmitter: only the included DC 9V 1.2A adapter; its USB-C port does not charge it. Receiver: dock on the transmitter, or USB-C at 5V / 0.5A. |
| B-7 PSM | USB-C, or the charging case (5V adapter rated above 2A, about 4 hours for the case). The units charge in about 1.5 hours and can be used while charging. |
