2-Pack Vapcell P1422A AA 1.5V Constant Voltage USB-C Rechargeable Battery – Built-in Charger for Cameras, Flash & Game Controllers

Description

Experience consistent peak performance from your AA-powered devices with the Vapcell P1422A. This innovative battery delivers a rock-steady 1.5V constant voltage output and features a built-in USB-C charging port, eliminating the need for a separate charger. Simply plug it into any USB-C cable to recharge. Unlike standard alkaline or NiMH batteries that gradually fade as they drain, the P1422A maintains full voltage until completely depleted, ensuring your digital cameras, camera flashes, game controllers, smart door locks, and electric toothbrushes perform at their absolute best from start to finish. Important: While physically AA-sized, the built-in USB-C port and charging circuit may add approximately 1–2mm in length. Please verify fit in devices with extremely tight battery compartments. This is a 1.5V battery—it cannot be used as a 3.7V lithium-ion cell.

Key Features

• 1.5V Constant Voltage Output – Delivers unwavering 1.5V power throughout the entire discharge cycle. Your camera flash recycles faster, your game controller's vibration stays strong, and your flashlight brightness never dims—unlike NiMH or alkaline cells that drop in voltage as they drain.

• Built-in USB-C Charging Port – Recharge directly from any USB-C cable connected to a wall adapter, power bank, laptop, or car charger. No separate AA battery charger required. The built-in LED indicator glows red while charging and turns green when fully charged.

• High Usable Capacity – Internal 2200mAh (3.7V) lithium cell provides approximately 900–1000mAh of usable energy at the regulated 1.5V output. Significantly outperforms standard NiMH AA batteries in high-drain devices like camera flashes.

• AA-Sized with Built-in Protection – Same physical footprint as a standard AA battery. Integrated circuit provides overcharge, over-discharge, and short-circuit protection for safe, worry-free operation. Due to the USB-C port, overall length may be approximately 1–2mm longer than a standard AA cell.

• Extremely Long Cycle Life – Retains over 80% capacity after hundreds of charge/discharge cycles, dramatically reducing long-term battery costs and environmental waste compared to disposable alkalines.

• 2-Pack Convenience – Perfect for high-drain devices that typically drain batteries in pairs, such as digital cameras, camera flashes, and game controllers.

Parameters

Applications

Recommended For

• Digital Cameras & Camera Flashes: Constant 1.5V ensures fast flash recycle times and prevents premature shutdowns due to low voltage. Far superior to NiMH batteries for photography.

• Game Controllers (Xbox, etc.): Maintains stable voltage for consistent haptic feedback and wireless performance throughout long gaming sessions. USB-C charging is more convenient than swapping AA cells.

• Smart Door Locks & Security Devices: Reliable power output ensures motor-driven deadbolts operate with full torque. USB-C port allows easy periodic recharging without removing the battery from the door.

• Electric Toothbrushes & Shavers: Constant voltage keeps motor speed steady for optimal cleaning performance. No more gradual power loss mid-brush.

• Wireless Mice & Keyboards: High capacity and low self-discharge provide months of use between charges.

• High-Output LED Flashlights (AA): Brightness stays constant from the first minute to the last, unlike alkaline or NiMH cells.

• Remote Controls & Smart Home Sensors: Long cycle life makes these ideal for frequently used devices.

Not Recommended For

• Devices Requiring More Than 2–3A Continuous Current: The internal regulation circuit limits maximum output current.

• Extremely Tight AA Battery Compartments: The USB-C port increases overall length by approximately 1–2mm. Some devices with rigid battery slots may not close properly. Always measure your device's battery compartment before ordering.

• Use as a 3.7V Lithium-Ion Cell: This is a 1.5V constant voltage battery. Do not attempt to use it in devices that require 3.7V power.

• Standard NiMH/Alkaline AA Chargers: Never place this battery in a conventional AA charger. It is charged exclusively through its built-in USB-C port.

FAQ

Q: How does this battery compare to regular NiMH rechargeable AA batteries?
A: NiMH batteries are 1.2V and drop in voltage as they discharge, causing flashlights to dim and camera flashes to slow down. The P1422A delivers a constant 1.5V until completely empty, meaning your devices perform at maximum power the entire time. It also charges directly via USB-C, eliminating the need for a dedicated NiMH charger.

Q: Will this battery fit my device? It says AA size.
A: It fits the vast majority of AA-powered devices. However, the built-in USB-C charging port adds approximately 1–2mm to the overall length compared to a standard AA battery. Most spring-loaded battery compartments accommodate this easily. Some devices with rigid, tight-fitting battery slots (such as certain blood pressure monitors or compact toys) may have difficulty closing. Please check your device's battery compartment depth before ordering.

Q: Can I charge this with a standard AA battery charger?
A: No. You must charge this battery using its built-in USB-C port with a standard USB-C cable connected to a 5V USB power source. Placing it in a conventional NiMH or alkaline charger will not charge the battery and could damage the charger or the battery.

Q: Can I use this battery for vaping or other high-drain applications?
A: No. The P1422A is designed for consumer electronics drawing up to approximately 2–3A. It is not suitable for high-power vaping devices or power tools. For those applications, use dedicated high-drain 18650 or 21700 cells.

Q: What is the actual capacity? The box says 2200mAh.
A: The 2200mAh refers to the internal 3.7V lithium cell's capacity. After voltage conversion to a regulated 1.5V output, the usable capacity is approximately 900–1000mAh. This is comparable to or better than a high-quality NiMH AA battery in high-drain devices, and the constant voltage provides a superior user experience.

Q: How should I store these batteries when not in use?
A: Store at approximately 40–50% charge in a cool, dry place. Use a non-conductive battery case to prevent short circuits. The USB-C port makes it easy to top up before use after storage.
