1. Dissatisfied with the charging of the car’s emergency starting power supply
the reason:
Insufficient charging current and voltage
Circuit board (MCU) problem
Suggestions for data line problems
solution:
Contact factory after-sales service

2. The car emergency start power plug is hot
the reason:
Poor contact of the plug will produce contact resistance, and this part of the electrical energy will be converted into heat and released
solution:
The power supply current is fast, so it will generate heat, which is a common phenomenon, but it should not be charged for too long.

3. The short life of the car emergency starting power supply
the reason:
The life span of the car’s emergency starting power supply is affected by many factors, the most direct factor is the life of the battery
solution:
Under the premise of normal use: use new imported high-rate lithium batteries

4. The car’s emergency starting power supply cannot be charged
the reason:
The problem is likely to be a short circuit inside the car’s emergency starting power supply
solution
It is recommended to contact the manufacturer for after-sales service

5. The capacity is false, and the gap is large
the reason:
The industry’s standards are not uniform.
solution:
Choose a regular car emergency starter power brand merchant

6. The car emergency start power indicator does not light up
the reason:
The internal battery is too low to be charged in time;
The output socket or output connection line is faulty (some car emergency start power load open circuit indicator does not light);
The power supply itself is faulty (such as poor contact of the charging input socket or damage to the internal circuit);
The indicator light (LED) is damaged.
solution:
Contact the manufacturer for after-sales maintenance

7. The power supply heats up severely when charging
the reason:
If the heat is severe, the charger power may be too high, or the battery may be aging.
solution:
Replace the charger with a lower power (try to use the original battery), or replace the battery

8. The car’s emergency starting power supply exploded
the reason:
Lithium-ion batteries will appear “dendrite phenomenon” during overcharging and discharging;
The car’s emergency starting power inverter is not shut down;
Friction between the USB interface copper sheet on the power supply and other metal objects may also cause spontaneous combustion.
Solution: Choose a better quality power adapter, and be careful not to press, drop, or vibrate strongly to avoid short circuits

9. Can’t charge half of the charge
the reason:
When using the car’s emergency power supply, it did not fully charge itself, so it was only half charged when charging;
The vehicle emergency start power supply is a virtual standard, and the actual capacity can only be half full;
Maybe the emergency power supply for the car you bought is broken and cannot be charged.
solution:
Choose regular brand merchants

10. The connection does not respond, nor can it be charged
the reason:
The charging cable is in poor contact or damaged, and the power supply itself has quality problems
solution:
Replace the charging cable, or directly contact after-sales repair

11. The car’s emergency starting power supply is charging normally, but it can’t output
the reason:
The output interface is damaged, the internal resistance is burned
Solution: Contact after-sales service to replace the internal resistance

12. After fully charged, it cannot be automatically powered off
the reason:
The protection board has no automatic protection function or the protection function is damaged
solution:
Choose a car emergency power supply with automatic protection function and good quality

13. The car emergency starting power supply does not store power
the reason:
The internal battery cell is damaged, or it has been aged for too long
solution:
Replace the battery or replace the finished product
