Vapcell Q2S-C USB-C Dual Bay Battery Charger

The Vapcell Q2S-C USB-C Dual Bay Battery Charger is a compact and convenient charger for one or two compatible 3.6V/3.7V rechargeable Li-ion or IMR cells. Featuring two independently managed charging bays, a modern USB-C input and a 1A charging current per slot, it is an excellent everyday solution for users of removable 18650, 20700, 21700, 26650 and other compatible cylindrical batteries.

Each charging bay operates independently, allowing the Q2S-C to charge a single compatible cell or two compatible cells at the same time. Charging stops automatically at 4.2V ±1%, while manufacturer-listed reverse-polarity, overcharge and over-discharge protection helps provide straightforward and dependable operation.

Why Choose the Vapcell Q2S-C Battery Charger?

• Two independent charging bays: charge one or two compatible batteries, with each channel controlled independently.
• USB-C power input: connect the charger to a suitable regulated 5V/2A USB power source.
• 1A charging current per slot: both bays can deliver a constant 1A charging current when used with the required power source.
• Automatic charging cut-off: charging stops automatically when the cell reaches the specified 4.2V ±1% cut-off voltage.
• Wide battery compatibility: suitable for popular 18650, 20700, 21700 and 26650 cells, as well as many additional cylindrical lithium-ion formats.
• Reverse-polarity protection: helps protect the charger if a battery is inserted in the wrong direction.
• Compact portable design: useful at home, at work or while travelling with an appropriate USB power source.
• Cable and manual included: the retail package contains the charger, USB cable and user manual.

Independent Dual-Bay Charging

The Vapcell Q2S-C uses two independent charging channels. You can therefore charge one compatible cell on its own or charge two compatible cells simultaneously. Because the slots operate separately, each bay manages its own charging process rather than treating both batteries as a matched pair.

This makes the Q2S-C particularly useful for removable-battery vape devices, torches and other compatible equipment that may use either a single cell or a pair of cylindrical lithium-ion batteries.

USB-C 5V/2A Power Input

The charger is powered through its USB-C input and requires a regulated DC 5V/2A source for full two-slot operation. Use the supplied cable with a suitable USB wall adaptor, power bank or other stable USB power source capable of providing the required output.

Vapcell does not advertise USB Power Delivery, Quick Charge or guaranteed USB-C-to-USB-C negotiation for this model. For the most reliable operation, use the supplied cable and a conventional regulated 5V/2A USB source unless your power-source compatibility has been confirmed.

Compatible Battery Types and Sizes

The Q2S-C is designed for rechargeable 3.6V/3.7V cylindrical Li-ion and IMR batteries measuring approximately 10–26mm in diameter and 34–72mm in length.

Manufacturer-listed compatible sizes include:

10340, 10440, 14500, 16340, 16650, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 20650, 20700, 21700, 22500, 22650, 25500, 26500 and 26650.

Battery construction can vary between manufacturers. Protected cells, button-top cells and cells with additional protection circuits may be longer than their nominal size. Always check the battery's actual dimensions against the 10–26mm diameter and 34–72mm length limits before ordering.
