If the electrical cables on your school’s Surface Pro 2 power adapters have started fraying, you’re not alone. It’s a common fault with the systems and for safety’s sake, it makes sense to get rid of them right away. After all, the shorted circuits can cause them to overheat or worse.
Since all SP2 systems are long off warranty, you’ll need to get a replacement power supply. Happily, there are a multitude of choices when it comes to solving your Surface Pro power problems.
For most, the first stop will be the online Microsoft Store to get a direct replacement adapter. If you like, you can get the exact replacement adapter (model 1536) from Microsoft for $80. It puts out the same 48-watts that the Surface Pro 2 needs to recharge and has a USB port for charging a phone or tablet at the same time. It should fit right in with a magnetic power port that snaps right into the SP2. That said, you can do better on price.
To start, you can get the exact same adapter from Delta, the OEM manufacturer that makes the original for Microsoft. It costs $38 – half as much and not only puts out a steady 12-volt stream at up to 48-watts it looks the same and comes with the needed magnetic power cord. Like the original, it has the Surface Pro 2’s oddball magnetic power port and you can plug it right into an AC outlet or use the included cord. A bonus is that the power brick has a USB power port.
Runpower has a clone of the Surface Pro 2’s original AC adapter that sells for less than $25 – one-third that of the Microsoft adapter -- yet matches the original 48-watt adapter spec for spec. It not only has the SP2’s unique magnetic plug, but the same bulky AC plug. Like the original, it also has the handy USB power outlet for charging a phone or tablet and is thermally protected against overloads.
A good stand-in for the Microsoft original is Laptop Charger Factory’s $23 replacement AC adapter. Although its 45-watt output is a little below-spec and might require slightly more time to get a full charge, you probably won’t notice the difference. It has the Surface Pro 2’s magnetic power plug and has a big bonus: you can plug the Laptop Charger Factory's AC adapter right into an AC outlet rather than using a traditional power cord.
At about $16, Bolweo’s Surface Pro 2 power adapter is a bargain basement power supply and one-fifth the cost of the Microsoft replacement device. On the downside, it puts out only 43- versus 48-watts for the original device, so you might need to spend some extra time charging the system’s battery pack. The Bolweo adapter may be larger and not look like the original, but it has the SP2 unique magnetic connector, is UL certified, supplies the right voltage and protects against overheating or overcharging.
