Aqiila Rechargable 18650 Battery USB-C Lithium 3.7V/2000mAh

Aqiila Rechargeable 18650 Battery USB-C Lithium 3.7V/2000mAh: Recharge directly by USB-C

The defining choice on the Aqiila Rechargeable 18650 Battery USB-C Lithium 3.7V/2000mAh is its built-in USB-C charging port, so you can recharge the cell directly rather than using a separate battery charger. It’s a 3.7V, 2000mAh lithium-ion 18650 battery for equipment that takes this cell type. Aqiila lists uses including headlamps, GPS devices, cameras, radios, torches and action cameras, making it relevant for both everyday kit and equipment taken outdoors. The stated capacity is suited to replacing a compatible 18650 cell, while the USB-C connection is a particularly handy detail when you already carry a USB-C cable. There’s no separate charging dock to pack for this battery. That direct-charge format is the main point to weigh up: the cell still needs to match the device, but charging doesn’t require a dedicated 18650 charger. The manufacturer also specifies more than 1,000 charging cycles and a maximum continuous discharge current of 5A. Those figures give you useful reference points for frequent use and for devices with higher power demands. Check the fit and battery requirements of your equipment before buying; the 18650 format and electrical values are the details to compare.

What it does

• USB-C charging: The charging port is integrated into the battery, so a separate charger isn’t required. Aqiila gives a full-charge time of around four hours, a useful detail if you’re planning when to top up a cell between outings.
• 2000mAh capacity: This is the battery’s stated capacity at 3.7V. It provides a clear figure to compare with the requirements of equipment that uses an 18650 cell, rather than relying on a general description of battery life.
• 5A continuous discharge: Aqiila specifies a maximum continuous discharge current of 5A. That’s relevant when comparing the battery with devices that draw more power, including the torches and action cameras named for this type of cell.
• Up to 18.5W output: The stated maximum output power is 18.5W. It’s a separate rating from the 5A continuous discharge figure, and gives another concrete point to compare against the power needs of compatible equipment.
• More than 1,000 charge cycles: Aqiila says the battery is designed to withstand over 1,000 charging cycles. For someone who recharges regularly, that figure indicates the intended repeated-use life, rather than treating the cell as a one-off power source.
• Li-ion cell: The battery uses lithium-ion chemistry. Its 18650 format, chemistry and electrical ratings are all worth matching to the battery specified for your device; the familiar cell shape alone doesn’t establish compatibility.
• Low self-discharge: The supplier describes the battery as having low self-discharge. That’s relevant when a charged spare spends time packed away between uses, such as a headlamp or GPS being kept ready for a trip.

Good to know

Aqiila specifies a charging temperature range of 0°C to 50°C, and a discharge range of -10°C to 50°C. Storage has its own stated range: -10°C to 35°C. These limits are useful to keep in mind for outdoor equipment, where a battery may be charged, used and stored in different conditions. They’re separate operating details, not a substitute for checking the requirements of the device taking the cell.
