What are the impacts of using a Surface Pro 4 charger on a Surface Pro 7?

Question

The specifications for both chargers are different:

Surface Pro 4: 12 volts @2.58 amps

Surface Pro 7+: 15 volts @4 amps

So I would like to know if using a lower amperage charger on the Surface Pro 7 could impact the battery life of the tablet.

Thank you in advance!

Hi Melissa,

Surface power supplies can be used across devices, but they don't all provide the same amount of power to keep your device charged. You want to use a power supply that provides at least the same wattage as the power supply that was designed for your Surface.

Surface Pro 4 provides 31W while Surface Pro 7+ was designed for 60W.

Hi MelissaP_002!

Thanks for reaching Microsoft Community. We're here to help and let's work on this together.

With your query, using a Surface Pro 4 charger on a Surface Pro 7+ may not provide enough power to charge the device properly, and it may take longer to charge the battery. However, it should not have any negative impact on the battery life of the tablet. It is important to note that using a charger with a lower voltage or amperage than what is recommended for your device may cause damage to the device and is not recommended. It is always best to use the charger that is specifically designed for your Surface Pro 7+ to ensure optimal performance and to avoid any potential damage to the device.

Hope this helps!
