The answer in two lines
A wall USB socket turns household mains into low-voltage 5 V power for charging, and the 2.1 A on the product page is the total output of both ports together. All pre-Power-Delivery USB power is at 5 V (Wikipedia), so 2.1 A is about 10.5 W by calculation (5 × 2.1), in line with Apple's well-known 5 V, 2.1 A iPad charger (Yahoo Tech). It should suit phones and tablets but not laptops, and installation is for a qualified electrician or engineer.
Want to charge your phone from a socket by the bed or sofa without a plug-in charger? In this guide from Tawredaat (توريدات), an electrical and finishing materials supplier in Cairo and Giza, we explain what a wall USB socket does, what 2.1 A means, what it can charge and where to fit it, using the named sources at the end.
Safety first: switch off the supply at the breaker before any work on the socket; installation, wiring and testing are for a qualified electrician or engineer.
What does a wall USB charging socket actually do?
It is a wall socket with two USB ports instead of (or beside) the usual plug openings, giving a low-voltage output for charging so you need no separate adapter. According to Wikipedia, USB downstream connectors supply power at a nominal 5 V DC, and all pre-Power-Delivery USB power is provided at 5 V. Our product page says two USB ports with a total output of 2.1 A, but it does not state the input voltage or the port type (Type-A or Type-C), so this article assumes neither.
What does 2.1 A mean?
The ampere is the unit of current. The product page says "dual USB ports with a total output of 2.1A", meaning 2.1 A is the total the socket can supply to both ports together, not per port. If you charge two devices at once the current is shared, and the pair cannot draw more than that figure in total.
Since USB runs at 5 V (Wikipedia), power in watts = volts × amps = 5 × 2.1 = about 10.5 W. For comparison, Apple's iPad charger is labelled 5 V at 2.1 A, which is 10 W (Yahoo Tech), and Apple's smaller 5 W adapter still charges an iPad but at a much slower rate (Yahoo Tech). The official USB Battery Charging specification allows charging ports up to 1.5 A (7.5 W) at 5 V (Wikipedia), and a plain USB 2.0 high-power device can draw up to 500 mA (Wikipedia, USB hardware).
| Reference | Current / power | Source |
|---|---|---|
| Plain USB 2.0 port (high-power device) | Up to 500 mA (2.5 W) | Wikipedia, USB hardware |
| Battery Charging port | Up to 1.5 A (7.5 W) at 5 V | Wikipedia, USB |
| Apple iPad charger | 5 V × 2.1 A = 10 W | Yahoo Tech |
| Nuovo NUV 80 907 wall USB socket (per the page) | 2.1 A total for both ports (about 10.5 W at 5 V) | Product page + calculation |
- ✔ 2.1 A is the most the socket can supply; the device draws what it needs, and the USB figures in the sources are "up to" limits, not fixed values.
- ⚠ Do not assume fast charging. The page does not mention QC, PD or any fast-charge technology.
Can it charge a phone, a tablet or a laptop?
We stay with figures from the sources and the page, and we give no fixed charge times because they depend on the device and its battery:
| Device | Suitable? | Why and source |
|---|---|---|
| Phone | Usually yes | Charger outputs in the sources run from 5 W (1 A) to 10 W (Yahoo Tech); 5 V at 2.1 A covers that. Check your phone charger's rating. |
| Tablet | Usually yes | Apple's own iPad charger is 5 V at 2.1 A (Yahoo Tech). For other tablets, check the rating on the original charger. |
| Laptop | No, do not rely on it | USB laptop charging is normally done with Power Delivery, up to 100 W at 20 V (Wikipedia, USB); the product page mentions neither PD nor any voltage other than 5 V. We do not recommend it. |
| Two devices at once | Current is shared | 2.1 A is the total for both ports (product page), so charging together may be slower. |
Note: "usually yes" means the figure covers the phone and tablet chargers named in the sources; your device maker is the final reference. The product page gives no list of compatible devices.
Where should you fit it at home?
According to the product page the socket is 22 mm deep, fits standard wall boxes and uses heat-resistant materials, so any place with a standard wall box suits it size-wise. Practical places to think about:
- ✔ Beside the bed, so the phone charges overnight without a loose charger.
- ✔ Beside the sofa or a seating corner for phones and tablets.
- ✔ In a desk or work corner for small devices.
- ⚠ Do not fit it where water can reach it directly. The product page gives no IP rating.
- ⚠ Check the wall box has room for the socket and its wires. The page only says 22 mm depth and standard wall boxes.
How do you fit it safely?
Wiring is done on the mains in the wall, so it is a job for a qualified person. Safe means the breaker is off and a qualified electrician or engineer confirms there is no voltage before touching any wire. If the breaker trips often after fitting, see our breakers, wires and panel guide or call a qualified electrician.
- ✔ Switch off the main breaker and confirm no power with a tester before touching anything.
- ✔ Check the wall box is standard and deep enough for a 22 mm socket.
- ✔ Use a qualified electrician or engineer for wiring and testing.
- ⚠ The product page does not state input voltage, overload or short-circuit protection or certificates, so we do not claim them. Read the manufacturer's manual if needed.

Frequently asked questions
Is 2.1 A per port or for both?
The product page says "dual USB ports with a total output of 2.1A", so it is the total for both ports together.
Does it charge a phone and a tablet?
Usually yes: 5 V at 2.1 A (about 10 W) matches Apple's original iPad charger (Yahoo Tech) and covers common phone chargers, but check your own device's charger rating.
Does it charge a laptop?
We do not recommend it. Laptops are normally charged with USB Power Delivery up to 100 W (Wikipedia), and the product page does not mention PD.
Does it get warm?
Any device that converts power can warm up slightly, and the page says it uses heat-resistant materials. We have no source for specific temperatures. If it gets unusually hot or smells, switch off the breaker and call a qualified electrician.
Is it suitable for a child's room?
The product page does not mention child-protection shutters. With small children, ask an electrical engineer for the best solution and choose a spot out of reach.
Can I fit it myself?
We do not advise it. Wiring is done on the mains in the wall and should be done by a qualified electrician or engineer after switching off the breaker.
