Use the charger without a voltage converter when the local supply voltage and frequency match its specifications and the supply can deliver the required current. Add a plug adapter only when the plug does not fit the outlet. A plug adapter changes plug fit, not voltage; a voltage-conversion setup addresses a voltage mismatch but must also provide compatible frequency and adequate current capacity.
Check the Vipboss charger
The Vipboss 36V 25A Lithium Battery Charger lists a 90–260 Vac input range, 115–230 Vac nominal input voltage, and 50/60 Hz nominal input frequency.
Make the choice

- Voltage and frequency match the listed specifications, and the plug fits: Use the charger without a plug adapter or voltage converter.
- Voltage and frequency match, but the plug does not fit: Use a plug adapter. It changes the plug’s physical fit, not the supply voltage.
- Supply voltage is outside the 90–260 Vac input range: A plug adapter cannot correct the mismatch. Use the charger only if a suitable voltage-conversion setup supplies voltage within the charger’s listed range, can deliver the required current, and leaves the supply frequency compatible. Otherwise, do not use that supply.
- Supply frequency is outside the listed 50/60 Hz specification: A plug adapter or voltage-only converter does not resolve the frequency mismatch. Use the charger only with a compatible frequency or with equipment specifically designed to address that frequency requirement.
The HSE guidance electrically powered equipment advises checking that the supply voltage is correct and that the supply can deliver the current the equipment requires. This check is separate from plug fit.
FAQs
Does a wide-voltage charger need a plug adapter when traveling?
Only when the charger's plug does not physically fit the local outlet. A plug adapter changes the connection shape; it does not change the supply voltage or frequency.
When would a wide-voltage charger need a voltage converter?
A converter is relevant only when the local supply voltage falls outside the charger's stated input range. The conversion equipment must deliver voltage within that range, support the required current, and leave the frequency compatible with the charger.
Can a plug adapter fix an incompatible supply frequency?
No. A plug adapter does not change frequency, and a voltage-only converter may not change it either. If the local frequency is outside the charger's listed specification, use a compatible supply or equipment specifically designed to address the frequency requirement.
