What the differences mean
A KVM dock charges laptops from its own power adapter. Price divided by the watts it can deliver to laptops at the same time gives what each charging watt costs:
- AV Access iDock C20: 60 W × 2 = 120 W; $259.99 ÷ 120 W = $2.17/W. Its adapter is 20 V × 10 A = 200 W, so 200 − 120 = 80 W is left for the dock and its ports.
- IOGEAR Dock Pro Duo: 100 W × 2 = 200 W; $299.95 ÷ 200 W = $1.50/W, but only with DisplayLink installed on both computers.
- StarTech 129N: 90 W + 45 W = 135 W; $294.99 ÷ 135 W = $2.19/W.
- AV Access iDock M10: $289.99 ÷ 100 W = $2.90/W, for the MacBook only.
- Sabrent SB-TB4K: $299.99 ÷ 60 W = $5.00/W, one laptop at a time.
- TESmart HDC202-X24: $699.00 ÷ 60 W = $11.65/W, about 5.4× the C20's rate ($11.65 ÷ $2.17).
- AV Access KD-E10: 12 V × 3 A = 36 W. That powers the dock, so the laptop still charges from its own charger plugged into the dock.

What each dock's charging figure really covers
The wattage printed on a KVM dock can mean three different things: power to each laptop at the same time, power only to the laptop you've switched to, or your own charger passing through the dock.
- Both laptops at once: AV Access says the iDock C20 "provides power to both connected laptops simultaneously" at up to 60 W each. Dock Gear HQ lists the IOGEAR Dock Pro Duo at 100 W to each of two hosts from a 230 W supply.
- Active laptop full, idle laptop reduced: Dock Gear HQ gives the StarTech 129N 90 W to the active laptop and 45 W to the standby one, from a 180 W adapter.
- Active laptop only: Dan S. Charlton found the Sabrent SB-TB4K "limited to 60W – and only one laptop charges at a time" from its 120 W supply. TESmart's HDC202-X24 charges only the laptop on PC1, at 60 W, and TESmart warns that laptops without 20 V charging may get only 7.5 W.
- Pass-through: the KD-E10 lists up to 100 W to the laptop, but AV Access says "please additionally use your laptop's original adapter". The dock's own 12 V 3 A adapter only powers the dock.
The iDock C20's low price per watt comes with limits. AV Access says macOS doesn't support USB-C MST, so a MacBook's two screens mirror. A 5120×1440 super-ultrawide is limited to 3840×1080, and four of its USB-A ports are USB 2.0. The two DisplayLink docks extend two screens on a Mac, but they need the driver on every computer, and ThunderboltLaptop reports that the StarTech blocks DRM-protected video.
Not recommended
Sabrent Thunderbolt 4 KVM Switch (SB-TB4K). On 2026-11-10 Sabrent's own US store listed it at $299.99 but unavailable. It charges only the active laptop at 60 W, and Dan S. Charlton measured about 5 seconds for monitors to come back after a switch (USB devices took 1-2 seconds). Sabrent also warns it is "for use with Thunderbolt-certified host systems only. Permanent damage can occur when used with uncertified devices."
