MARSDOCK 65W Surface Charger with 20W USB-C & 10ft Cable

MARSDOCK's 65W replacement charger powers Microsoft Surface devices and fast-charges a phone simultaneously via a 20W USB‑C port, all through a long 10‑foot magnetic cable.

Designed as a high-performance alternative to OEM adapters, this MARSDOCK charger combines a 65W Surface-compatible output with an additional 20W USB‑C port for charging a second device at full speed. The 10‑foot cable with a magnetic Surface plug gives flexible reach in living rooms, offices, and cars while smart charging circuitry helps maintain battery health and prevents common electrical faults.

Will this charger work with my Microsoft Surface model?

Yes — the adapter is built to be compatible with a wide range of Surface devices, from recent tablets to older laptops. It supports Surface Pro and Surface Laptop series, Surface Book and Studio generations, and Surface Go models listed in the compatibility set.

• Compatible with Surface Pro 11 through Pro 3 and Surface X
• Supports Surface Laptop generations 1–7 and Laptop Go models
• Works with Surface Book 1–3 and Studio (selected models)
• Includes magnetic Surface-style plug for simple connection

How fast will my laptop and phone charge together?

The adapter provides a total power budget of 85W across two outputs: 65W for the Surface connection and a 20W USB‑C port. This lets you charge a Surface at near‑full speed while topping up a phone; many modern phones reach roughly half battery in about 30 minutes on a 20W feed.

• 65W output optimized for Surface laptops and tablets
• 20W USB‑C port for rapid phone or accessory charging
• Simultaneous charging without significant throttling of either device
• Faster than common 44W or lower-output alternatives

What safety and battery-care features are included?

MARSDOCK built multiple protections into the adapter to guard against overcurrent, short circuits, and overheating. The internal charge management also learns usage patterns to limit stress on the battery, which helps reduce long-term capacity loss.

• Overcharge, overcurrent, short‑circuit, and thermal protection
• Smart charging algorithms to minimize battery aging
• Cool-blue LED status indicator for immediate power feedback
• Important safety guidance: avoid charging on soft surfaces to prevent blocked ventilation

How convenient is the 10‑foot magnetic cable in everyday use?

The extended cable length and magnetic plug make it easier to charge while sitting on sofas, working at desks, or using the backseat during travel. The magnetized connector snaps in place without precise aiming, reducing wear and accidental disconnection.

• 10‑foot cable gives wide reach across rooms and vehicles
• High‑sensitivity magnetic plug for quick, tool‑free attachment
• Plug‑and‑play design reduces strain on device ports
• LED indicator near the adapter reveals charging status at a glance

Who is this for: MARSDOCK's 65W Surface charger is aimed at Surface owners who want a reliable, long‑reach replacement or travel charger that can also fast-charge a phone. It's well suited to professionals and students who need flexible charging at home, in transit, or in shared workspaces and prefer a single adapter that safely handles both laptop and mobile power needs.
