Can I use a charger with lower voltage than the original?

Voltage too low – If the voltage on an adapter is lower than the device, but the current is the same, then the device may work, albeit erratically. Usually, an under-voltage condition won’t cause damage or shorten the life of your device.

What happens if I charge with lower voltage?

Yes it will discharge the battery if it was fully charged. The charging source will become a sink (the current will reverse direction from your battery to the “source”) to the lower voltage and the battery will eventually stay at this (insufficient) voltage level.

Can low voltage damage Chargers?

You can check on the side of your charging cable for the specifications (usually somewhere around 100-240 Volts). If the low voltage is outside this range, it can damage the power supply and possibly the battery or laptop.

Is it bad to charge your phone with low voltage?

Charging you phone with lower voltage is actually good for it’s battery life, but it takes more time to charge. For example: charging it with computer/laptop’s USB port.

Can I use a charger that provides the same voltage but a different amperage?

No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.

Can I use a charger with a lower wattage?

You can not use a charger with a lower wattage rating. A 30W or a 45W charger can not supply sufficient power for your laptops needs which means you could damage the laptop and/or the charger.

Can I use 65w charger instead of 45W?

As long as it is the same voltage and connector type you can use a higher watt adapter. It will charge the battery a bit faster but other than and the size of the brick you will see no difference.

Can I use a battery with lower voltage?

You can safely use it to charge a Lithium-ion battery provided that you have mechanisms in place to handle fault conditions such as an over-discharged battery (must be charged at a lower current until reaching 3.0V/cell), charger malfunction (not limiting current or voltage), cell voltage imbalance, and excessively …

Can I charge my phone with a lower wattage charger?

No. The power rating of a charger has no bearing on the life of the battery nor the consumption of power by the device. A higher wattage charger only means it can supply up to the specified amount of current, not that it will push that amount of current to the device.
