Is the higher the voltage of the rechargeable flashlight?
The rechargeable electric drill, battery voltage level, not good or bad, as long as you pay attention to the charging power output type electric drill on the line, the size of the output power, direct impact drill drilling effort size.
When the output power of rechargeable power drill is the same, the higher the voltage, the smaller the rated current, because the power is equal to the product of the voltage and current. For example, long distance power transmission is the use of high voltage to reduce the delivery of electricity, although the high voltage line is thin, but it can deliver a lot of power.
