Titan Taichi 2in1 USB charger

First one USB charger with car battery tester in the world. This innovative combination leads the world. It not only charges your 3C devices in the car, but also detects car battery output voltage condition at the same time in order to avoid running out your car battery or detect battery life condition. For charger function, it features 2.5A max output fitting all mobile devices and 12V/24V auto switch function. Easy-carrying and Taichi pattern design presenting Chinese Yin-Yang connection (Chinese Philosophy about dualism) are also the emphasis of 2 in 1 function: USB charger and car battery tester totally satisfy your demands.

1) Innovative combination: USB charger and Car battery tester
2) MAX 2.5 A output fits every mobile device
3) 2/4 USB ports satisfy different devices charging at the same time
4) 12V/24V auto switch function

Notice before using

** This USB charger is not compatible with Samsung Tab series. ** Condition on testing car batteryï¼? 1. 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. 2. Before igniting the car, LED lights indicate car battery condition (After igniting the car, generator voltage showing on LED without indication range) A. red/yellow/green - battery voltage > 12.5V (25.2V), means good condition B. red/yellow - battery voltage from 11.8V ~ 12.5V(24V~25.1V), means normal condition C. 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.

ã?Quick Reference for Car Battery Capacity ã?? 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 % 12.2V~12.4V 50 % 12.0V~12.2V 40 % 11.8V~12.0V < 40% <11.8V

ã?Important knowledge for monitoring voltageã?? 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)
