Microsoft Surface 36W Charger — 12V Surface Connect

The Microsoft Surface 36W Charger is a 12V Surface Connect power adapter associated with Microsoft power supply Model 1625. It delivers 12V at 2.58A, or approximately 31W to the Surface device, with an additional 5W USB charging output bringing the adapter's combined rating to 36W. Microsoft identifies Model 1625 with Surface Pro 3 and standard Surface Pro 4 configurations.

Why Is a 31W Charger Often Called 36W?

The difference comes from the additional USB charging port. The main Surface output is 12V × 2.58A, approximately 31W, while the built-in USB port provides another 5V × 1A, or 5W. Together, these outputs give the power supply its commonly used 36W total rating.

This means the core Surface charging specifications to match are:

• 12V DC Surface output
• 2.58A Surface output current
• Approximately 31W delivered to the Surface
• 5V / 1A auxiliary USB output
• 36W combined adapter rating

Which Surface Models Use the 12V Model 1625 Charger?

The Microsoft Surface 36W Charger is directly associated with the Surface Pro 3 and Surface Pro 4. Microsoft's current charging documentation specifies Model 1625 at 12V / 2.58A for these devices.

One important exception is the Surface Pro 4 Core m3 configuration, for which Microsoft lists the 24W Model 1735 charger instead. This is why checking the exact Surface model and current charger label is useful before placing an order.

12V or 15V? Don't Choose by Connector Alone

Several Microsoft Surface chargers use the same magnetic Surface Connect style while operating at different voltages and wattages. Later adapters commonly use 15V, whereas Model 1625 supplies 12V at 2.58A. A connector that physically fits is therefore not enough on its own to identify the correct replacement.

For a straightforward compatibility check, look for Model 1625, 12V, and 2.58A on your existing adapter.

A Practical Replacement for Older Surface Pro Systems

For Surface Pro 3 and compatible Surface Pro 4 users in Dubai and across the UAE, the Microsoft Surface 36W Charger provides the correct legacy 12V charging profile without confusing it with later higher-voltage Surface adapters.
