How many doors do PowerBox charging lockers come in?

Four, eight, ten and sixteen doors, each available with a flat or sloping top. Compartment sizes are 300 × 300 mm, 300 × 450 mm, 380 × 450 mm and 450 × 450 mm.

Which size is best value per compartment?

The 8-door bank. At £987.31 for the full 3-pin mains plus USB-A and USB-C specification it costs only £11.59 more than the 4-door at £975.72 and gives twice the compartments — £123.41 per compartment against £243.93. The cheapest compartment in the range is the 16-door mains-only bank at £66.17.

How much does a sloping top add?

A flat £24.76–£24.78 regardless of bank size, so it works out at 3.0% on a 10-door mains unit and 1.4% on a 16-door mains-plus-USB unit. A sloping top stops bags and cups being left on the roof of the locker, which matters most in corridors and reception areas.

What colours are available?

Three carcass colours — black, silver and white — and seven door colours: black, blue, green, red, silver, white and yellow. All are powder-coated over cold-rolled mild steel.

Does each compartment charge independently?

Yes. Every compartment has its own charging outlet behind its own locked door, so a device charges without sharing a socket or leaving a charger out in the open.

Do charging lockers need an electrician to install?

The locker bank needs a mains supply at its installed position, so a competent electrician should make the final connection and the installation should be inspected and tested to BS 7671 like any other fixed electrical equipment. Plan the socket position before the lockers arrive — moving a bank after installation is the expensive part.

Can USB-C charge a laptop in these lockers?

USB-C outlets suit phones, tablets and low-draw USB-C devices. For a full laptop on its own charger, specify a bank with a 3-pin UK mains socket — the mains-plus-USB models cover both in one bank. If laptops are the main use case, see the UK mains charging lockers.

USB-C Charging Lockers

USB-C charging lockers let staff, students or visitors secure a device and charge it over the modern USB-C standard at the same time — no trailing chargers, no shared sockets, no flat batteries at handover. Every locker in this range is a Probe PowerBox locker fitted with a USB-C outlet inside each compartment, so the device charges safely behind a locked door.

What's in this range

These are Probe PowerBox lockers configured with USB-C charging — supplied in 4, 8, 10 and 16-door layouts, with a choice of flat top or sloping top. Most models pair USB-C with a USB-A outlet, and several add a 3-pin UK mains socket as well, so one bank can charge a mix of phones, tablets and USB-C laptops. The lockers are built to the same cold-rolled mild-steel Probe specification as the rest of our metal lockers, powder-coated and made in the UK.

Choosing USB-C charging lockers

Device mix — USB-C suits recent phones, tablets and USB-C laptops. If you also charge older kit, choose a model that adds USB-A or a 3-pin mains socket.
Compartment count — 10-door gives larger compartments for tablets and small laptops; 16-door packs in more phone-sized bays per footprint.
Top style — sloping tops deter clutter and sitting in busy corridors; flat tops keep the usable surface and overall height lower.
Locking — a Type A cam lock on every compartment, fitted as standard. No hasp, padlock, coin-return or electronic option is stated in the Probe product data.

Door count is the price decision, not the charging type

Across the whole PowerBox range the cost per lockable compartment falls sharply as the bank gets bigger, and the step from four doors to eight is the one worth knowing about:

Bank	Charging	From	Per compartment
4 door, flat top	3-pin mains + USB-A + USB-C	£975.72	£243.93
8 door, flat top	3-pin mains + USB-A + USB-C	£987.31	£123.41
10 door, flat top	3-pin mains + USB-A + USB-C	£1,164.50	£116.45
16 door, flat top	3-pin mains + USB-A + USB-C	£1,770.61	£110.66
10 door, flat top	3-pin mains only	£838.96	£83.90
16 door, flat top	3-pin mains only	£1,058.65	£66.17

The four-door bank costs £11.59 less than the eight-door and gives you half the compartments. Unless the alcove genuinely will not take the taller unit, the eight-door is the better buy at almost identical money. Beyond that the curve flattens: the sixteen-door reaches £110.66 per compartment on the full mains-plus-USB specification, and a mains-only 16-door bank is the cheapest compartment in the range at £66.17.

The sloping top is a flat charge, not a percentage. It adds £24.76–£24.78 whatever the size of the bank — so it costs 3.0% on a 10-door mains unit and only 1.4% on a 16-door mains-plus-USB unit. If you want a sloping top to stop items being left on the roof, it gets proportionally cheaper the bigger the bank you buy.

Every bank shares the same Probe specification: cold-rolled mild steel, powder-coated, three carcass colours (black, silver, white) and seven door colours (black, blue, green, red, silver, white, yellow), in 300 × 300, 300 × 450, 380 × 450 and 450 × 450 mm compartment sizes.
