1. Look at the starting current
The most important indicator of the starting power supply is **"starting current"**. Simply put, it is how much power is needed to start a car.
Sedan ➜ Choose at least 600A
SUV, van ➜ Choose 1000A or more
Large-displacement diesel car ➜ Choose 1500A or more
2. Look at the battery capacity
The battery capacity determines how many times you can use it once it is fully charged, and also affects the time it takes to charge mobile phones and other devices with USB.
Recommended for home use: ≥8000mAh
Commercial or long-distance travel: ≥12000mAh
Most popular models on e-commerce platforms are between 10000~20000mAh
3. Check safety protection functions
When purchasing a starting power supply, be sure to pay attention to whether there are the following intelligent protection functions:
Reverse connection protection (prevent reverse connection of the battery)
Overcharge and over-discharge protection
Short circuit protection
Overheat protection
4. Whether it is multifunctional
USB (charges mobile phones, tablets, and driving recorders)
LED lighting (for emergency repairs and lighting at night)
SOS flashing light (emergency distress signal)
Digital display screen (visible remaining power)
5. Portability and appearance design
Nowadays, many starters are very small, and some are even lighter than a mobile phone. They do not take up space when you go out and can be easily put into the glove box. You can also choose a style with a storage bag for easy storage and carrying.
