Frequent Questions and Answer:
Q1: How does this car charger detect voltage?
A: Compared to other digital car chargers, our cigarette lighter voltage meter uses the various elegant colors of LED lights to inform you of the voltage ratios in your car at a glance. White light indicates voltage is normal, red light means voltage is abnormal (below 10.8V) For your own safety, if red traffic lights light up, please check your vehicle immediately to avoid safety risks. This is the jumping point of this design.
Q2: Is this quickly calculated for my Galaxy S10?
A: With a total output of 4.8A, the charging speed of the car charger is higher compared to 2A and 1A. However, because Qualcomm Quick Charge is not supported, the charging side does not show fast charge when charging.
Q3: Does the charger sit flush in the cigarette lighter?
A: Our mini charger fits perfectly with most car models as the size of the cigarette lighter depends on different brands. The charger may be shorter or longer than the cover, but does not affect the charging function. (If you have problems with the size of the charger and have any concerns, please let us know immediately, we will solve your problem within 24 hours.)
Q4: Is it easy to remove the charger from the cigarette lighter?
A: Yes, you can take it out easily. It fits tightly to the cigarette light, but the socket of each car is slightly different.
Q5: Will the LED indicator distract at night?
A: Absolutely not, the soft LED light will show you the voltage of the car while not distracting you when driving. White indicator means stable voltage; red indicator means voltage is below 10.8V. The USB car charger indicator will not light up if it is too strong or too short circuited.
