Yes. A charger marked 90–260V AC, 50/60Hz is rated for input voltages from 90 through 260 volts and for either 50 or 60 hertz. Both 110V and 220V fall within that voltage range; 50Hz and 60Hz are both listed frequencies. Read the charger's input rating as a pair: the supply voltage must be within the stated range, and its frequency must be one the charger lists.
How to read the two input ratings
The voltage range gives the low and high AC input limits. A nominal 110V supply is between 90V and 260V, as is a nominal 220V supply. The range does not mean the charger changes its battery output voltage to match the wall supply; it describes the AC power the charger accepts.
The frequency entry is separate. 50/60Hz means the charger is rated for both 50Hz and 60Hz input. If a label lists only one frequency, do not assume the other is supported just because the voltage is in range. Compare the supply voltage with the charger's voltage range and the supply frequency with its frequency rating. The Vipboss 36V 25A lithium battery charger is specified for 90–260Vac input at 50/60Hz, so both 110V and 220V, at either listed frequency, fall within those stated input ratings. Its stated output is 43.8V at 25A for 36V LiFePO4 batteries.
FAQs
Can a 90–260V, 50/60Hz charger be plugged into both 110V and 220V outlets?
Yes, provided the actual supply voltage is between 90V and 260V AC and the supply frequency is 50Hz or 60Hz. The charger input rating covers both nominal 110V and nominal 220V supplies, but the plug and outlet must also be compatible.
Does the charger produce a different battery voltage when the wall voltage changes?
No. The 90–260V rating describes the AC power the charger can accept from the wall. The charger still provides its specified DC output for the intended battery system rather than changing the battery voltage to match the outlet.
What should I verify besides the 110V or 220V supply voltage?
Check that the supply frequency is 50Hz or 60Hz, the outlet and plug are suitable, and the circuit can provide the required input current. Also confirm that the charger's output voltage, current, connector, polarity, and battery chemistry match the battery.
