Product Highlights:
1.Smart chip:
Ensure your safety and stability when using. The chip adds an automatic protection mechanism. When it encounters overcurrent, overload, and short circuit, it will automatically cut off power to prevent accidents
2.Working silently:
It emits a subtle sound of less than 25 decibels during charging, which makes it very quiet, so there is no need to worry about noise.
3. Intelligent protection:
worry-free power supply: stable output voltage, high use efficiency, filter function, multi-layer protection, wide range of use, portable use, flame-retardant housing, LED work indicator.

AC Adapter 9V 1A Application:
widely compatible,5.5mm * 2.5mm universal DC output. Suitable for most 9V 1A devices: Arduino UNO R3 / Nixie tube clock / Elegoo, IEIK UNO R3 / MEGA 2560 / Schwinn elliptical machine, schwinn bike, hybrid trainer, and other devices require 9V and less than 1000mA.

Notes on using the power adapter:
1.Be careful not to squeeze the power adapter cable and cause the outer insulation sleeve of the power cable to break.
2.Do not allow the power cable to bear for a long time and cause damage to the power cable.
3.Do not use in humid or high temperature environment.
