Notice
** This USB charger is not compatible with Samsung Tab series.
** Condition on testing car battery
- Adjust tester switch depending on car output voltage. General speaking, 12V for normal cars and 24V for trucks etc. Then plug in cigarette adapter position with Taichi 2in1 USB charger.
- Before igniting the car, LED lights indicate car battery condition (After igniting the car, generator voltage showing on LED without indication range)
red/yellow/green - battery voltage > 12.5V (25.2V), means good condition
red/yellow - battery voltage from 11.8V ~ 12.5V(24V~25.1V), means normal condition
red - battery voltage < 11.8V (24V), means poor condition, please start your car right away. If only red light appears often, that means car battery is almost dead.
【Quick Reference for Car Battery Capacity 】
Capacity | 12V car battery | LED Light |

100 % | >13.0V | ![]() |
90 % | 12.8V~13.0V | ![]() |
80 % | 12.6V~12.8V | ![]() |
70 % | 12.4V~12.6V | ![]() |
60 % | 2.2V~12.4V | ![]() |

40 % | 11.8V~12.0V | ![]() |
< 40% | <11.8V | ![]() |
【Important knowledge for monitoring voltage】
Normal car battery voltage is over 12V, and operating voltage 14V±0.5V appears after starting the generator; If voltage is under 12V when you turn the power on, it should be the problem of weak car battery, electric leakage on circuit or long term without igniting the car.
11V or lower voltage should not appear at the moment igniting the car. If voltage is under 11V, we need to start the generator to charge it or change a new one depending how long we bought the battery (except long term without usage)
