How to Charge a COSLUS Water Flosser

Charging a COSLUS water flosser is straightforward: connect the charging cable to the flosser, then plug it into a compatible power adapter. Make sure the charging port is dry before connecting the cable.

COSLUS also offers a water flosser power adapter as a separate accessory for users who need a compatible adapter for charging.

How to Charge Your COSLUS Water Flosser

1. Turn the water flosser off.
2. Dry the charging area. 
   Make sure there is no water around the charging port before connecting the cable.
3. Connect the charging cable to the water flosser.
4. Plug the cable into a compatible power adapter.
5. Connect the adapter to a wall outlet.
6. Check the charging indicator to make sure charging has started.
7. Disconnect the charger when charging is complete.

The exact indicator behavior and charging time can vary by model, so check the manual for your specific COSLUS water flosser.

Which Power Adapter Should You Use?

Use a 5V USB power adapter rated up to 2A to charge your COSLUS water flosser.

A wall adapter is not included in the package. If you need one, COSLUS sells a separate Water Flosser Power Adapter on its website.

How Long Does a COSLUS Water Flosser Take to Charge?

Charging time depends on the model.

For example, the COSLUS E40 takes about 4 hours for a full charge according to its user manual.

Other COSLUS models may have different battery capacities or charging times, so it is better to check the manual rather than assume every model charges at the same speed.

How Do You Know When It Is Charging?

The charging indicator depends on the model.

On the COSLUS E40, the battery indicator flashes while charging. After the battery is fully charged, the indicator stays on briefly and then turns off.

For other models, check the user guide for the exact indicator pattern.

Can You Charge a COSLUS Water Flosser Right After Using It?

Yes, but make sure the charging port is dry first.

If the device is wet from use, wipe the charging area and wait until there is no visible moisture before connecting the cable.

That is probably the most important charging habit to remember with any cordless water flosser.

What If Your COSLUS Water Flosser Is Not Charging?

Start with the simple stuff:

• Make sure the cable is fully connected
• Check that the charging port is dry
• Try a different wall outlet
• Make sure the power adapter is working
• Look for the charging indicator
• Check the cable for visible damage

If it still will not charge, check the troubleshooting section in the manual for your model or contact COSLUS support.

Can You Use a COSLUS Water Flosser While It Is Charging?

Do not use the water flosser while it is connected to the charger unless the manual for your specific model says otherwise.

Charge it first, unplug it, and then use it normally.

Bottom Line

To charge a COSLUS water flosser, turn it off, make sure the charging port is dry, connect the charging cable, and plug it into a compatible power adapter.

Charging time and indicator behavior vary by model, so check the user manual for those details. If you need a wall adapter, COSLUS also sells a dedicated Water Flosser Power Adapter separately.
