Belkin RockStar 10-Port USB Charging Station — 10x USB-A, Charge Only
10 USB-A portsUp to 2.4A per portCharge only, no dataWall or desk mountFanless
The Belkin RockStar B2B139 is a ten-port USB-A charging station built for the situation where a room full of phones, tablets or Chromebooks all need charging overnight. Each port delivers up to 2.4 A with intelligent device detection, so it gives each device what it asks for rather than a fixed trickle.
It is charge only — there is no data path at all, and Belkin does not claim MFi certification. That is a design decision rather than an omission: for a classroom or a stockroom cart you usually want power without any host connection.
Compatibility — check before buying:
Ten standard USB-A ports, so any device that charges from USB-A works — phones, tablets, Chromebooks with USB-A charging, handhelds, scanners. One important number: the power supply is rated at 120 W, but Belkin’s own FAQ caps real output at 21 A, which is 105 W. Ten ports at 2.4 A each would be 24 A, so all ten cannot draw the full 2.4 A simultaneously. Plan around 105 W of usable output, not 120 W. It is fanless, has an anti-slip base and overcurrent protection, and mounts on a wall or sits on a desk. There is no rack option and no cable management — and no cables are supplied.
Best For
✓Classrooms, training rooms and libraries charging a set of tablets or Chromebooks overnight
✓Stockrooms and back offices keeping handhelds, scanners and phones topped up
✓Any shared space where ten devices need power and none of them should be able to talk to a host
Key Features
Ten ports from one socket
Replaces ten wall plugs. Each port has intelligent device detection so it negotiates the right current for what is connected rather than forcing one profile.
Charge only, no data path
No sync, no host connection, nothing for a device to negotiate with beyond power. On shared and student devices that is usually exactly what you want.
Fanless and wall mountable
Silent in a classroom, with an anti-slip base for desk use and wall mounting if you would rather get it off the surface.
Overcurrent protection built in
Belkin fits overcurrent protection. Note that this is not a surge protector — Belkin’s own FAQ says so explicitly, even though a regional page advertises a Connected Equipment Warranty.

Frequently Asked Questions
Is it really 120W?
The power supply is rated 120 W, but Belkin’s FAQ gives the actual output as 21 A, which is 105 W. Ten ports at 2.4 A each would need 24 A, so all ten cannot pull maximum current simultaneously. Size your deployment around 105 W.
Does it sync data as well as charge?
No. It is charge only. There is no data path and no host connection.
Does it include a cart or dividers for tablets?
No. This is the bare charging station. Belkin sells separate Store and Charge products with cart, dividers and cable management — do not assume those features from listings that mix the ranges.
Is it a surge protector?
Belkin’s FAQ says it does not include surge protection, while a Belkin UK page advertises a Connected Equipment Warranty for surges and lightning. Those two statements do not agree. Treat it as an unprotected charger and use a surge-protected outlet if that matters.
Are cables included?
No. You supply the USB cables for whatever you are charging.
Singular Expert Insight
The number to plan around is 105 W, not 120 W — that is Belkin’s own figure and it means ten tablets pulling hard will not all get 2.4 A. For a classroom trolley charging overnight that is irrelevant; for ten devices being fast-topped-up in a twenty-minute break it is not. Also note this is the bare station: no cables, no cart, no dividers, no cable management.
