USB Module USB A + A 50mm: Charging Speed Myths Busted

The 15.5W ceiling is shared, not per port

The Buster + Punch USB MODULE / USB A + A / 50 MM is a double USB A charger module. Its catalog output is 5V DC 3.1A, 15.5W max. That figure describes the module as a whole, not each port. Plugging two devices into a double USB socket module does not double the available power; the 15.5W ceiling is shared between them.

This is the first USB charging speed myth to retire: more ports does not mean more total watts. If you charge a phone and a tablet together, expect the module to divide its output rather than deliver 3.1A to each.

What the catalog actually confirms about output

• USB MODULE / USB A + A / 50 MM: 5V DC 3.1A Output, 15.5W Max. Sets the real power ceiling for the whole module, so you can judge charging expectations without relying on port-count assumptions.

  

• USB MODULE / USB A + A / 50 MM: Double USB A charger module, suitable for charging portable devices. Confirms the module's purpose is charging, but does not promise fast-charge standards or per-port current.

Three USB charging speed myths that affect this module

• Myth: a double USB socket module gives each port the full amperage: The catalog lists 3.1A as the module's output, not per-port output. Treat 3.1A as a shared budget across both USB A ports.
• Myth: higher amperage always means faster charging for every device: The supplied information does not list supported fast-charge protocols, so you cannot assume any particular phone or tablet will charge at its top speed. The module supplies 5V DC up to 3.1A total; the device's own charging behavior is not specified here.
• Myth: any 50mm wall plate will fit this module: Compatibility is narrower than the 50mm label suggests. The module is compatible with Buster + Punch UK 50mm Euro Plates, but not with UK 45mm Module Plates or EU Electricity Plates.

Fit is a separate decision from charging speed

Before debating watts, confirm the plate. The USB A + A module is built for Buster + Punch UK 50mm Euro Plates. It is not compatible with UK 45mm Module Plates or EU Electricity Plates. That single compatibility line matters more than any charging-speed claim, because an incompatible plate makes the module unusable in your wall.

If you already own a 45mm module plate or an EU electricity plate, this is not the module for that setup. Check your existing plate standard before ordering, and if you are unsure which plate you have, consult a licensed electrician rather than guessing.

Compatibility evidence for the 50mm USB A + A module

• USB MODULE / USB A + A / 50 MM: Compatible with Buster + Punch UK 50mm Euro Plates. This is the plate family the module is designed to fit.
• USB MODULE / USB A + A / 50 MM: Not compatible with UK 45mm Module Plates or EU Electricity Plates. Rules out two common plate types, so you can avoid a return before you buy.

What the supplied information does not tell you

The catalog does not list supported fast-charge standards, per-port current limits, cable requirements, or standby power use. It also does not provide installation steps. Those gaps are decision limits, not proof that the module lacks a feature. If your purchase depends on a specific fast-charge protocol, the supplied evidence cannot confirm it, so ask before you buy or choose a module whose documentation states the protocol explicitly.

The catalog also notes that you should see the tech spec for more information and consult a licensed electrician if in doubt. Treat those as the correct next steps for installation and any electrical uncertainty.

Buying advice for a double USB socket module

• Start with the plate, not the wattage: Confirm you have or will install a Buster + Punch UK 50mm Euro Plate. If you have a 45mm module plate or an EU electricity plate, stop here.
• Budget the 15.5W across both ports: Plan for shared output. If you routinely charge two power-hungry devices at once, expect slower charging than either device would get alone.
• Ask about fast-charge support if it matters to you: The supplied record does not confirm any fast-charge standard. If your phone or tablet needs a specific protocol, verify it before purchase.
• Use a licensed electrician when in doubt: The catalog explicitly advises consulting a licensed electrician if you are unsure. Installation guidance is not supplied here.

Price and finish context

• USB MODULE / USB A + A / 50 MM: Catalog price USD 46.97 (comparison price USD 77.00). Gives you the current listed price and a reference point without implying a temporary promotion.
• USB MODULE / USB A + A / 50 MM: Available finish: WHITE. Confirms the finish option shown in the catalog so you can match your plate and room scheme.
