Pre purchase instructions

The product has a maximum charging power of 50w and a maximum discharge power of 45w. Only 2 batteries can be installed internally, so there are extremely high requirements for battery performance and internal resistance. Customers who purchase spare parts must use 21700 batteries with a discharge rate of 5c or above, otherwise the battery temperature will be very high during high-power charging and discharging.

Introduction to Product Capacity and Volume

Introduction to Product Capacity and Volume

This mobile power supply is currently the smallest among the mobile power supplies with monitors in our store, with a size of only 84 * 54 * 39mm. The size is smaller than the size of a pack of cigarettes. Although small in size, its performance is also very powerful, with a discharge capacity of over 45W. Two high-quality 21700 batteries provide 10000mah of power.

Product advantages

The shell of this product is the same as the common 2-section transparent mobile power supply on the market last year, with three colors. The transparent shell can visually see the internal circuit. However, the mobile power supply of the same shape and style on the market is 22.5w maximum power. Our mobile power supply has reached 45W and no display. It uses Nixie tube to display the power and cannot display other parameters. We use Smart Display and high-quality battery. It is more suitable for short distance travel and meets more usage needs and hobbies.

Each interface can also display real-time load conditions, and there will also be a display when the device is plugged in. It can display information such as the voltage of each battery, total voltage, current, temperature, percentage of battery charge, etc. For those who like to view monitor data, it is very suitable. The screen display UI design is beautiful, the data is comprehensive, and the logo is also comprehensive. At a low price, it can enhance the visual and experiential experience.

Port

The product has a total of 4 interfaces, all data cables can be used. Apple Lightning input. Type-c input output. Use two outputs.Two USB output.

Product circuit design and use

The product is designed as a single circuit, meaning that only one device can achieve maximum power. If two devices are inserted simultaneously, the output is 5v3a. The product supports both punching and discharging, which is also the maximum total power of 5v3a

DIY kit assembly

The product assembly is simple, with 2 sections of 21700 being welded in series. Finally, connect the wires on the battery pack to the motherboard. Attention should be paid to spot welding between batteries in order to generate excessive current, otherwise the contact points will generate heat and cause high temperatures in the battery.
