The main advantages of QI2.1 protocol (wireless charging standard) include:

#Charging power increase#
QI2.1 can track the position of the receiving coil in real time and achieve more efficient energy transmission by optimizing dynamic fine-tuning technology. The module supports a maximum charging power of 15W, which improves charging efficiency by about 30% compared to the previous generation

#Improved magnetic positioning accuracy#
Through magnetic array technology, the coil alignment error is controlled within ± 0.5mm, solving the alignment problem caused by mobile phone movement or magnetic attachments in traditional wireless charging, and greatly improving charging efficiency.

#Enhanced foreign object detection#
Adding a metal foreign object detection module can avoid heating or charging interruption problems caused by interference from coins, keys, etc.

#Device compatibility extension#
Supports compatibility between Apple and Android wireless charging, and is backward compatible with Qi1.3 and Qi2.0 devices.

Main selling point:

1. 3-in-1 Magnetic External Battery
Intelligent LCD Screen, Ql2.1 certification + Double Pop-up Widget(Dynamic Digital Display)

2. Built-in high energy Lithium Cobalt Oxide Battery,
5000/10000mAh large capacity

3. New Thermal Management Design，Built-in double-layer graphene thermal conductive layer and aerogel thermal insulation layer ,to ensure fast charging.low temperature and stable performance of the product.

4. AG frosted tempered glassback panel,Anti-fingerprint,Anti-scratch
Note：The back panel of the power bank is made of AG frosted tempered glass, so the display screen is a bit blurry, but you can still see the power, current and voltage digital display, and the advantage of frosted glass is scratch resistance and anti-fingerprint.
