Li-ion Battery LP18650A+ used for Digital Backpack

Li-ion Battery LP18650A+ used for Digital Backpack, Lithium-ion Batteries, and lithium-polymer Batteries are getting more popular in modern consumer electronics, LiPol manufacturers offer both lithium-ion batteries and lithium-polymer batteries.

Keeback is the first innovative backpack of its kind, which fundamentally changed the concept of technology bags. This simplified backpack with multimedia functions can meet your style needs. The true digital backpack comes from the future.

Unique design and appearance
The original backpack is made of high-quality parts. It has multimedia functions to truly show your style, especially if you are a designer, musician, DJ, biker, gadget lover, or fashion person.
We combine the concepts of “backpack” and “equipment.”
We installed 1044 light displays, 10W subwoofer, 13600mAh high capacity lithium-Ion battery, and 4X USB socket in Keeback. The total weight of the backpack is only 1.9 kg.
The first wearable technology backpack

Keeback has a customizable, flexible RGB display with 1044 pixel animation, text, music spectrometer, etc. The backpack with a built-in LP18650A+ 4P 14Ah lithium-ion battery display is the next-generation technology package. This is a speaker manufacturer cooperating with the world’s leading brands. Keeback has a huge advantage. It can use ultra-lightweight housing and powerful 10W speakers to ensure immersive sound and deep bass.

Built-in animation, text, and spectrometer

You can use the “Apply” or “Mode” buttons at the bottom of Keeback to select an animation preset. Feel free to create your own image. We plan to add new animations every month. Besides, you can easily implement your ideas using Keeback open-source code.

Use Keeback on the street, especially at night, using the music spectrometer animation. This is a brand new thing you have never seen before. Our life-changing backpack will have a huge impact on your life, making it novel and interesting.

Have you ever ridden a horse with a backpack? In other cases, you can pack the device in your bag while walking or outside of Keeback. It is made of high-quality plastic and has a built-in high-capacity 14Ah lithium-ion battery. It is lightweight and can be worn in the sun, snow, and rain, but you can also take it to mountains, beaches, and almost anywhere with sufficient power.

If you want to change the animation or text saved in the Keeback system, you can easily open Keeback when you go somewhere, push the rubber cover at the bottom. You can also open the lid to choose what you like. Keeback is still a backpack, and you can put many items in it: documents, some cloth, or even a 13-inch laptop.
