Do all Surface Pro models use the same charger?

If you have owned more than one Microsoft Surface device, it is natural to wonder:
“Do all Surface Pro models use the same charger?” The short answer is no.
Most Surface Pro generations share the same type of connector (the magnetic Surface Connect port),
but they do not all use identical power adapters. Different models are designed for different power
requirements, and newer devices can also charge via USB-C Power Delivery (PD).

In this guide, we will break down how Surface Pro charging works, which models can share a charger,
what wattage you really need, and how to pick a safe replacement adapter.

1. Surface Connect vs USB-C: two charging “worlds”

Almost every Surface Pro generation from Surface Pro 3 onwards charges via the slim magnetic
Surface Connect port. Some newer models also support USB-C Power Delivery (PD), which
allows charging through a USB-C port as well.

• Surface Connect charger – the classic magnetic blade connector on the side of the device.
  This is still the primary and most common way to charge any Surface Pro.
• USB-C PD charger – supported by newer models such as Surface Pro 7, 7+, 8, 9 and Surface Pro X.
  These can charge from a properly specified USB-C PD adapter with the correct voltage and wattage.

So even before we discuss wattage, there are two questions:

1. Does your Surface Pro have a Surface Connect port? (Almost all do.)
2. Does your Surface Pro also support USB-C PD charging? (Only newer generations.)

2. Do all Surface Pro models use the same Surface Connect charger?

From a physical connector standpoint, most Surface Pro devices that use Surface Connect can plug
into the same style charger. However, not all adapters are identical internally. They vary by:

• Wattage (power rating) – e.g. 39 W, 44 W, 65 W.
• Current output – e.g. 15 V 2.58 A, 15 V 2.6 A, 15 V 4 A.
• Intended device class – smaller tablets vs higher-power Surface Pro and Surface Laptop models.

This means:

• Many Surface Pro models can share a charger as long as the connector is Surface Connect and
  the wattage is equal to or higher than the original.
• They do not all use exactly the same charger – a 39 W adapter and a 65 W adapter are
  not interchangeable in terms of performance, even though they fit into the same port.

As a rule of thumb:
it is safe to use a higher-wattage Surface Connect charger on a lower-power device,
but not the other way round.

3. Common Surface Pro charger wattages (with real-world examples)

Surface chargers are typically rated around 39–44 W for lighter devices and about
65 W for more demanding models or multi-purpose use.
Here are three example adapters that reflect the most common power levels:

15V 2.58A 44W Microsoft Surface Connect AC adapter

The 15V 2.58A 44W Surface Connect charger
is a classic power level used across many Surface Pro and related models.
It is ideal for everyday productivity, light multitasking and typical office work.

• Good match for many Surface Pro generations with moderate power needs.
• Balanced between performance and compact size.
• Suitable as a main home/office charger or a reliable spare adapter.

15V 2.6A 39W Microsoft 1963 Surface Connect AC adapter

The 15V 2.6A 39W “Model 1963” Surface charger
is typically used with smaller or more energy-efficient Surface devices.
It offers enough power for everyday tasks while keeping the adapter light and portable.

• Best for lower-power or compact Surface devices.
• Ideal as a travel charger thanks to its smaller size.
• Use on more demanding Surface Pro models only if 39 W meets the original spec.

15V 4A 65W Microsoft Surface Connect AC adapter

The 15V 4A 65W Surface Connect charger
is designed for higher-demand devices and users who keep multiple applications, external displays
or heavier workloads running.

• Recommended for many newer and more powerful Surface models.
• Helps prevent slow charging under heavy load.
• Safe to use on most Surface Pro devices that originally shipped with a lower-wattage adapter.

4. Can I share one Surface charger across different Surface Pro models?

In many situations, yes – as long as you follow these rules:

• Match the connector: the adapter must use the Surface Connect magnetic blade.
  Do not try to use barrel or unofficial connectors.
• Equal or higher wattage: a 65 W charger can safely power a device that came
  with 44 W, but using a 39 W charger on a 65 W device may cause slow charging or battery drain
  while in use.
• Use quality replacements: choose chargers with built-in over-voltage, over-current
  and over-temperature protection to safeguard your device.

In other words, the connector family is shared, but the ideal wattage is not identical for every model.
If you only own one Surface Pro, match the original specification. If you own multiple devices,
a higher-wattage adapter (such as 65 W) often works well as a “universal” Surface Connect charger
for the household or office.

5. What about USB-C chargers for Surface Pro?

Newer Surface Pro models (such as Surface Pro 7, 7+, 8, 9 and Surface Pro X) can also charge from
a USB-C PD adapter. However:

• Not all USB-C laptop chargers are the same.
• You need proper Power Delivery (PD) support, usually with a 15 V or 20 V profile.
• The adapter should provide at least 45 W, and ideally 60–65 W for smooth use.

Older models (for example Surface Pro 3–6) cannot charge via USB-C at all and must use
a Surface Connect charger. Even for newer devices, many users still prefer Surface Connect
for everyday use and keep USB-C as a flexible backup option.

6. How to choose the correct charger for your Surface Pro

If you are unsure which charger your Surface Pro needs, follow these steps:

1. Identify your exact model name under Settings > System > About
   (for example “Surface Pro 6”, “Surface Pro 7”, “Surface Pro 9”).
2. Check the rating on your old charger if you still have it:
   look for markings such as 15V 2.58A 44W or 15V 4A 65W.
3. Decide whether you want Surface Connect only or also USB-C flexibility
   (for newer models).
4. Use a specialist parts store that lists compatible models and clear
   output ratings on each product page.

On our Microsoft charger category, you can filter by type
and open each charger page to review compatible devices and technical specifications before you buy.

7. Conclusion: do all Surface Pro models use the same charger?

• Physically: most Surface Pro models share the same Surface Connect connector.
• Electrically: they use different wattages (e.g. 39 W, 44 W, 65 W) and some also support USB-C PD.
• Compatibility: a higher-wattage Surface Connect charger can usually be shared safely across models;
  a lower-wattage unit is not ideal for more demanding devices.
• Best practice: choose a charger that matches or exceeds your original wattage and is clearly listed as compatible with your exact Surface Pro model.

So while your Surface Pro may not use exactly the same charger as every other Surface Pro, finding
a safe and compatible replacement is straightforward once you know your model and power requirements.
A correctly specified charger will keep your Surface running reliably for work, study and travel – with
no surprises when the battery runs low.
