1. Depending on the time required for charging, choose a battery that can be fully charged in a short time, preferably within 2 hours.
Reason: The portable battery station is born for convenience. During the self-driving process, it can be fully charged by staying in a place with electricity for a short time. It can also be fully charged during short-distance driving.
2. Combined with the needs of use, look at the maximum power of the power supply and battery capacity.
Reason: If what you need is to boil water, the power you bought is only enough to power a light bulb; or you need to grill a skewer with your friends, but the battery capacity you bought is only enough to cook half-cooked, so what's the point. If you want to boil water for cooking, choose one with a power of 1600W~2200W, which is almost omnipotent.
3. Look at the price
Reason: Product quality, performance, and service life must match the price, as well as your wallet.
4. Look at the safety of battery cells
Reason: I have seen too many explosive news about electric vehicles. Try to choose lithium iron phosphate batteries, which are more secure.
5. see weight and size
Reason: Only if you can move it can it be called a "mobile" power supply. However, the lighter the better, combined with the performance, it is better to be below 15kg; if the size is too large, it will occupy the space of the trunk, and the maximum side size should not exceed 400mm.
6. Choose a big factory product
Reason: Small stores can easily buy portable battery stations assembled from used refurbished batteries.
