IQOS 3 DUO is charging slowly or not charging

1. Make sure you’re using our official cable and AC power adaptor. Charging your device from a computer USB port, rather than from an official AC adaptor, can be up to 4 times less effective. Similarly, using a third-party cable can be up to 5 times less effective.

2. If your Pocket Charger is already fully charged when you connect it to a power supply, the last status light may blink. This is normal and does not indicate that your Pocket Charger is unable to charge. Conversely, if your Pocket Charger has been completely discharged, then it may need to be plugged in with an official AC adaptor for up to 20 minutes before any status light patterns appear.

3. If your Holder is not charging properly, it might be that the connectors need cleaning. Just clean the connectors of your Holder and the Pocket Charger with the device Cleaning Sticks.

1. If they’re blinking white twice: Your device may be outside the operating temperature range (0°C-50°C). Alternatively, your Holder may need to be inserted into the Pocket Charger with the Door closed for auto-cleaning.

2. If they’re blinking red: Reset your device. If the red lights persist, contact customer care.

Will your device not start? Does it feel difficult to draw on your tobacco sticks while using your device? Not getting enough aerosol when using your device? These issues can likely be resolved by using our Cleaning Tool and Cleaning Sticks.

Cleaning your device regularly and with the right tools will not only ensure that you are getting the optimal experience; but it can also solve some of the issues you may be experiencing with your device.

IQOS 3 DUO has physical damage or broken blade

1. Check to see if your device has a broken heating blade or any other physical damage. If it does, we are sorry that this happened to you. Please contact Customer Care and we will support you with this issue.

Sometimes the cleaning of the Holder can damage the blade inside your Holder. Be careful not to exert force onto the blade when cleaning your Holder. Also, ensure you never twist your heatstick while it’s in the Holder. This movement can damage the heating blade and disrupt your experience.
