This tool functions as a current converter / home AC power source converter (220v) into a DC power source (48V) so you can use all DC equipment (6-48 volts) ranging from car vacuum cleaners, car sound systems, even charging batteries you are in an emergency (power supply) .
The ideal load is + 80% of the ability of the adapter, so for example if you buy a 20ampere adapter then the maximum load is 20 amperes x 80% = 16 amperes (use of an adapter with a load current above that causes the power supply to be easily damaged / burned)
How to calculate your electricity needs your amperage
watt / voltage = ampere
so for example if your electronic equipment is 100 watt voltage then 12v
100 watts / 48volt = 2,083 Amperes
Following is the choice of AC 220 to DC 12volt ampere converter
- 1 ampere
- 2.1 amperes
- 4 amperes
- 7.3 amperes
- 10 amperes
