As a replacement or backup, this 65W Surface Pro Laptop Charger does exactly what it’s supposed to. It delivers the necessary power to keep your Surface Pro 9 charged and ready to go. The build quality feels decent, with a sturdy cable that doesn’t seem like it will fray easily with regular use.
I did notice that the charging brick itself gets noticeably warm after an extended period of charging, which isn’t necessarily a dealbreaker but is something to be aware of. It’s not hot enough to be concerning, but it’s a tangible warmth. The compact design is appreciated for portability, fitting easily into a backpack side pocket.
This charger is ideal for anyone who needs a reliable, no-frills power source for their Surface Pro 9, especially if they’ve misplaced their original or want a spare for the office. However, if you’re looking for a power bank with additional features like USB-C ports for other devices, you’ll need to look elsewhere.

The build feels robust, with a matte finish that resists fingerprints quite well.
I found the sheer capacity to be a lifesaver during a recent long travel day. It charged my Surface Pro 9 from near empty to full, and still had plenty of juice left for my phone.

However, the sheer size and weight of this unit are its most significant drawbacks; it’s definitely not a pocket-friendly device.
This Anker power bank is perfect for frequent travelers, digital nomads, or anyone who needs to power multiple high-demand devices on the go. If you prioritize portability above all else and only need to charge a single device occasionally, this might be overkill and too heavy for your needs.

The 65W PD output is more than sufficient for most Surface Pro 9 charging needs, ensuring it doesn’t take an eternity to replenish. The textured, grippy surface feels secure in hand, which is a plus when you’re on the move.

Frequently Asked Questions
Can Any USB-C Power Bank Charge My Surface Pro 9?
Not all USB-C power banks are suitable. Your Surface Pro 9 requires a substantial amount of power. It needs a power bank that supports USB Power Delivery (PD).
Specifically, look for a power bank with a high wattage output, ideally 45W or more. A lower wattage might charge it very slowly or not at all. Always check the power bank’s specifications carefully.
How Many Times Can a 20,000mah Power Bank Charge My Surface Pro 9?
A 20,000mAh power bank can typically charge a Surface Pro 9 about once. The Surface Pro 9 has a battery capacity of around 47.7Wh. Power banks lose some energy during charging.
This energy loss is due to heat and the conversion process. Therefore, you won’t get the full advertised capacity. Expect roughly 13,000-15,000mAh of usable output from a 20,000mAh unit.
Is It Safe to Charge My Surface Pro 9 with a Power Bank?
Yes, it is generally safe. Use a high-quality power bank from a reputable brand. Ensure it supports USB Power Delivery (PD) at the correct wattage.
Reputable brands include safety features like overcharge and short-circuit protection. These prevent damage to your device. Avoid cheap, unbranded power banks that lack these safety measures.
What Is the Difference Between USB-a and USB-C for Power Banks?
USB-A is an older standard. It typically offers slower charging speeds. USB-C is a newer, more versatile standard. It supports higher power delivery and faster charging.
For your Surface Pro 9, USB-C PD is essential. It allows for efficient and rapid charging. USB-A ports on a power bank might be useful for older devices, but not for the primary charging of your laptop.
Can I Use a Power Bank While My Surface Pro 9 Is on?
Yes, you can charge your Surface Pro 9 with a power bank while it is powered on. The power bank will help maintain or increase the battery level.
However, demanding tasks might still drain the battery faster than the power bank can charge it. This is especially true if the power bank’s output wattage is not high enough. For the fastest charging, it’s best to charge when the device is off or asleep.
Final Verdict
For the Surface Pro 9, the Anker 737 Power Bank (PowerCore 24K) is the top recommendation. It boasts a 24,000mAh capacity and an impressive 140W total output, with a 100W USB-C PD port capable of fast-charging the Surface Pro 9. Its robust build quality and reliable brand reputation ensure safety and longevity, making it the ideal companion for your device.
