Performance Result
Never misses your work or any important stuff again with depleted car battery. Yup, aLLreLi car charger constantly monitors your car battery voltage. And will display “LOW” alert light if voltage drops below normal level. That’s the feature that every car charger should have. I missed to work due to this issue once. Luckily, it is not happening when outstation. Else I am stuck in the wild. By the way, don’t forget that it also have over voltage, overheating and overcurrent protection as part of its safety technology.

Vehicle battery voltage

I am getting maximum charging rate from aLLreLi charger no doubt. It manages to charge Onda V820w tablet and Honor 5X smartphone at the same time as below picture. 2.4A port is charging Onda V820w while 1A port is charging Honor 5X. However, I am facing a problem here. The 1A port can’t charge Onda V820w at all. The LED screen will keep flashing and won’t charge anything then. After testings, I found out that 1A port is limited to devices that require 1A current only. Can’t work on 2A devices like Galaxy S4, iPad 3 and so on.
