Schwaiger Professional USB Fast Charger — Quick Charge 3.0, up to 18 W
QC 3.0 up to 18 W1x USB-A110–240 VWhite
The Schwaiger LAD440532 is a single-port USB-A wall charger with Qualcomm Quick Charge 3.0, delivering up to 18 W to compatible devices and 5 V / 2.4 A (12 W) to everything else, for charging phones, earbuds and small USB devices from a mains socket. It suits anyone who wants a compact spare charger for a QC-compatible Android phone or a reliable 12 W USB-A charger for other devices.
With Quick Charge 3.0 the charger steps voltage between 3.6–6 V (3 A), 6.2–9 V (2 A) and 9.2–12 V (1.5 A). Schwaiger states that compatible devices reach up to 80% in about 35 minutes. It has short-circuit, over-voltage and overload protection, accepts 110–240 V input and weighs 55 g.
Before you order: The plug is a Euro plug (type C). Cyprus wall sockets are BS 1363 (type G), so you need a Euro-to-UK adapter or a power strip that accepts Euro plugs. There is no USB-C port and no USB Power Delivery — iPhones and PD-only devices charge at the standard 12 W rate.
What's in the Box
- 1 x Schwaiger USB fast charger, white
- Operating instructions

What It Means in Practice
- QC 3.0 phones charge up to 18 W; other phones, earbuds and accessories charge at up to 12 W
- Use your existing USB-A cable (USB-A to USB-C, Micro-USB or Lightning)
- Wide 110–240 V input — also works when travelling outside Europe with the right plug adapter
- Protection against short circuit, over-voltage and overload
What Will Not Work
- No USB-C port and no USB Power Delivery
- Not for laptops — 18 W is too little for notebook charging

Which phones get the 18 W?
Phones supporting Qualcomm Quick Charge 3.0 (or backward-compatible QC 2.0). Others charge normally.
Singular Expert Insight · Buyer's Guide
Single-port QC 3.0 chargers are still the right fit for many Android phones and anything with a USB-A cable. If your phone uses USB-C Power Delivery, a USB-C PD charger is the better choice. For laptops, see our
laptop power supplies.
✓ Buy it if you have a Quick Charge 3.0 phone or USB-A devices and want a compact spare charger.
✕ Skip it if you need USB-C, Power Delivery, laptop charging or more than one port.
→ Also consider a USB-C PD charger for iPhone and recent Android phones.
