Buyers must read:

1, the product has a variety of shells, price consistent, no special requirements for random delivery, if you need to specify please leave a note or inform customer service.

2, the power adapter belongs to general electronic products, has been working continuously, the lamp will not change color. As long as the current, voltage and charging interface are consistent, can be universal.

3、This charger has 5 kinds of DC interface specifications,Before you take it, please be careful of the interface specifications. I don't know the interface specifications. Please contact the customer service or take advantage of the security option "power supply + full set of adapter""

4, how to determine charging interface?

Measure the diameter of the interface with a ruler. Case 5.5*2.5mm= outer diameter 5.5 mm / inner diameter 2.5 mm

In color classification, {power supply + full adapter head >}, the adapter can be used for all charging interfaces.

This product uses a new circuit board and components, 100% after 24 hours of aging.
