Features:

1. Place 3* 18650 flat head batteries, detachable, solderless DIY battery cases. (excluding batteries)

2. Battery level display, 4-level LED light displays battery level, intelligent automatic shutdown in non working state. (Note that the battery power is calculated using the voltage calculation method. Please use batteries with high performance and stable voltage. If the voltage drop of the battery is too poor, the indicator light's power will drop quickly, and the output will almost remain in the first and second grids of power.)

3. Unlike traditional non detachable mobile power supply covers, this one can be screwed on the back and can be opened repeatedly by removing the screws, allowing for easy replacement of battery cells.

4. Dual USB output port 5V/2.4A (MAX), micro/type c input port (PD charger not supported).

5. Compact and convenient, it is a good companion for home/outing/outdoor sports.

6. The motherboard is equipped with anti installation protection, and the battery is installed backwards without burning the motherboard. If reinstalled correctly, it can be used normally, but do not merge one positive and one negative into a damaged battery, damage the battery, or severely aged battery, otherwise it will cause direct short circuit and spring burning of the battery.

Before purchasing, you must read:

1: Battery that can be used: 18650 lithium battery (flat head without protective plate)

Requirements for connecting to batteries: 3.3-4.2V lithium batteries (18650 flat head lithium batteries): Do not connect to other batteries, such as 1.2V 18650 nickel hydrogen batteries, 3.2V iron lithium batteries, all dry batteries, and 12V lead-acid batteries

2: Charging and discharging protection: The circuit board is equipped with a built-in lithium battery protection IC, which includes overvoltage protection, overcurrent protection, undervoltage protection, etc

3: Three packs can accommodate up to three 18650 batteries (two packs, one pack is not a problem).

4: Charging input requirements: The most suitable charger is a 5V2A or higher charger, and any other 5V constant voltage power supply can be used as the charging input power supply. Note that PD chargers are not supported

5: After the battery is first connected, it is usually necessary to activate the circuit board to generate an output. If the mobile power supply is not used for a long time, the output will be turned off, and activation is still necessary.

Specifications:

Colors: black, white, blue, green

Cell type: 3.7V18650 battery (flat head, no protective plate, internal resistance less than 50 milliohms, 1C discharge rate, each voltage must be between 3.3 and 4.2V), cannot use pointed batteries, does not support modification or insertion of other batteries that do not meet the requirements!)

Dual USB output parameters: 5V/0.1-2.1A (high current devices, fast charging mobile phones, mobile phones with a screen size of 5 inches or more, high power, do not use batteries that are too poor, otherwise normal output and inaccurate battery power cannot be achieved.)

Input interface: Type-C port and Micro port (PD not supported)

Input parameter: Standard current 5V/0.1-2A

Packaging list:

1 * 3 18650 batteries mobile power supply housing
