Suitable for all kinds of high-power demand electrical device! Controller, Toys, Remote Controls, Smart home devices, Microphone, Electric shaver, Household Office Devices, Flashlight(The charging current of the flashlight is less than 2A to be used).(Not available on Camera Flash, Seiko R-Wave Mantel Clocks and AM Radio) Quick Charger Charging Time: About 2 hoursInput: Type-C 5V 2AOutput: 500mA*4ChIndependent charging channelCharging Voltage: 5V Red Indicator --- Charging Green Indicator --- Full charged (The blue light at the positive pole of the battery is up when charging, and goes off when the battery is full) Red flashing --- Error ----This charger is only for 1.5V rechargeable lithium batteries with battery identification and data reading, if you put in the wrong type of battery, the indicator light is blinking red and can't power the battery. Constant voltage output 1.5V Lithium-ion battery is a new generation of battery, so this Kratax charger is only suitable for this new type of battery, not for the traditional 3V-3.7V Li-ion battery. Constant Voltage Output Longer life than normal Alkaline batteries and other rechargeable battery. Stable outputs voltage from 100% to 0% electric capacity, 1.5V constant voltage output at 100mA discharge, providing constant voltage and best performance in high current and voltage device. Cost-effective Capacity: 3500mWh / 2300mAh Charging time is about half that of NiMH rechargeable batteries. Low self-discharge rate of about 0.03% per month, about 1/100th of that of NiMH batteries. Weighs about 19g, the NiMH battery is about 20% heavier. More Durable It is recommended to use Kratax battery and Kratax charger as a set, not to mix with other brands. QUESTIONS Q: Which one has a longer working time, Kratax constant voltage rechargeable lithium battery or disposable battery? A: Disposable batteries have a longer working time, but our lithium-ion batteries can be charged and discharged repeatedly, with a longer overall use time and a higher cost-effectiveness. Disposable batteries can maintain good performance in the initial use due to their higher voltage. As the use time increases, the performance gradually decreases until the user replaces the battery. Our lithium battery has a constant voltage, which allows the device to maintain the optimal performance within the settings until the battery stops outputting, so the working time of a single lithium-ion battery will be reduced by about half compared to disposable batteries. Q: Why do lithium-ion batteries feel a little bigger than alkaline batteries? A: The size of our battery is 50.5mm*14.6mm*14.6mm (L*W*H), because the lithium-ion battery is equipped with a protective plate, it may be 0.1~0.2mm larger than the length and diameter of a few alkaline batteries, mainly depends on What product to compare with.

Widely used This AA lithium battery up to 3A current, which can be better applied to high current devices, fit for game controller, outdoor camera, motorized toys, remote controls, smart home devices, microphone, medical devices etc. (Not applicable to camera flashes)

Stable output Kratax 1.5v rechargeable AA battery provide an approximately equal and stable voltage to the device until it runs out of power, the fully intelligent control IC chip makes it more reliable to use. The cycle time is more than 1600 times, one AA lithium battery is equivalent to 1600 disposable batteries.

Fast charging Compact size, 5V-2A input, about 2h charging time, half of the charging time of traditional AA Ni-MH rechargeable batteries; Automatic power off when fully charged, which is both safe and extends battery cycle life.

Multi-Protection Intelligent control of the entire charging process, built-in protection device to prevent overcharge, overvoltage, overcurrent, over discharge, the charger has reverse charge protection can protect the battery and charger very good. Our batteries and chargers have passed ROHS, CE, CQC, PSE, etc. certification.

More Durable Our AA lithium battery adopts the exhaust explosion-proof design, high safety level. Low self-discharge, is about 0.03% per month, which is less than 1/100 of Ni-MH batteries.The weight is about 19g, is 20% lower than Ni-MH batteries.
