1440 watts. The 12v120a generator is 1440 watts. The power of 12v120Ah is W = 12V multiplied by 120A = 1440 watts. If it is charged for 12 hours, it can be fully charged, which means the charging current of the charger is 10A. calculated that the power of the charger is 120W (the actual power is higher than this, because the charging voltage of the charger is higher than the rated voltage of the battery, and the charger itself must also consume power if the charger is 120 W). it will consume 1.44 degrees of energy for 12 hours of charging.
Generators are electrical products and their insulation performance compared to water is very important. Usually, not to mention using a water gun to spray, it is not allowed to work in a humid environment.
In order to enable generators to operate in different harsh environments, the Electrot Commissionechnique international has formulated protection level specifications for electrical products. The protection level of the product, such as IPxx, will be mandatory on the product nameplate of the generator.
IPxx protection level, where xx represents two digits. The numbers on the left and right represent the dust protection level and waterproof level, respectively.
The meaning of the numbers on the left:
The meaning of the numbers on the right:
According to the table above, the "IP21" in the The image depicts water or a product without moisture protection. If you want to get the protection ability of a water gun, the protection level should reach at least IPx6.
