20W USB-C PD · 18W USB-A · GaN · 41g · Smart IC · Universal · White

The charger that came with your phone is either slow, bulky, or both. GaN technology lets this one deliver 20W in a body that weighs 41g and fits in a shirt pocket — running cooler and wasting less energy than the brick on your bedside table.

Used daily by commuters, travellers, and desk workers who've replaced their standard charger and never looked back — one compact unit, two ports, full fast-charging speed.

✦  20W USB-C PD3.0  ·  ✦  18W USB-A  ·  ✦  GaN technology  ·  ✦  41g · Smart IC · 87.4% efficient · Universal 100–240V

Why GaN makes a real difference

Standard chargers use silicon components that generate significant heat and require more physical space to manage it. GaN (Gallium Nitride) is a more efficient semiconductor that converts power with less energy loss — which means less heat, a smaller body, and an efficiency rating of ~87.4% vs the 75–80% typical of standard chargers. Same output. Less waste. Smaller package.

Important to know

Single port speeds: 20W on USB-C and 18W on USB-A when each port is used alone. Combined output caps at 15W when both ports are active simultaneously — speeds distribute across both devices. For maximum fast charging, use one port at a time.

No cable included. Use your existing USB-C or USB-A cable. A USB-C to USB-C cable is recommended for iPhone 12+ and most modern Android phones to get full 20W PD speed.

Why you'll love it

20W USB-C PD3.0 — fast-charges iPhones and USB-C Android at full speed — Power Delivery 3.0 at 20W is the standard fast-charging speed for iPhone 12 through 17 and most modern USB-C Android flagships. Charge an iPhone from 0 to 50% in approximately 30 minutes — compared to over an hour on a standard 5W charger.
18W USB-A — fast-charges virtually every Android phone — the USB-A port delivers up to 18W, covering Quick Charge compatible Samsung, Huawei, Xiaomi, Redmi, Realme, and most Android devices. Connect a USB-A to USB-C or USB-A to Micro-USB cable and get fast charging without needing a second charger for older devices.
41g and smaller than a matchbox — travels anywhere — at 7.9×4×1.7cm and 41g, this is one of the most compact 20W chargers available. It weighs less than most coins combined. Drop it in a bag, jacket pocket, or toiletry bag and it disappears. Universal 100–240V input means it works in any country without an adapter.
Smart IC — auto-detects your device and adjusts output — the Smart IC chip identifies each connected device and delivers exactly the power it needs. No manual settings, no risk of over-voltage or under-voltage. Plug in and the charger handles the rest, with built-in protection against overheating, overcharging, and short circuits.

Frequently asked questions

Will it fast-charge my iPhone?

Yes — iPhone 12, 13, 14, 15, 16, and 17 series all support 20W fast charging via USB-C PD. Connect your iPhone using a USB-C to Lightning cable (iPhone 12–14) or USB-C to USB-C cable (iPhone 15–17) to the USB-C port for full 20W fast charging. Note: a compatible cable is required but not included.

Can I use both ports at the same time?

Yes — both ports work simultaneously. When both are active, the combined output caps at 15W (5V/3A), distributed between the two devices. For maximum fast charging speed on a single device, use one port with the other empty. For simultaneous charging of two devices (e.g. phone and earbuds), both will charge reliably at distributed speeds.
