4480W 350AJump Starter Power Station Energy Storage System Precautions for use: Generally speaking, the newly purchased outdoor mobile power supply is very low when it is used for the first time, so it is best to re-use electricity with full charge for the first time after purchase, which helps to improve the efficiency of the built-in lithium battery of the outdoor mobile power supply. It is normal for the outdoor mobile power supply to generate some heat during charging or discharging, but if your outdoor mobile power supply is very hot, there is a problem, which may be a problem with the charging circuit. Therefore, the purchase of outdoor mobile power must have over-rush and over-discharge circuit protection, the battery must be produced by a regular manufacturer, and the battery produced by a small factory must not be considered.
