USB-C is everywhere.
So is TheOne.
Almost everything you plug in today charges over USB-C. The real question is how long it takes — for your device, precisely. Look it up below.
Ten seconds to check
Your device, and
how long it takes.
Look yours up: the tool says whether it is compatible, at what power TheOne feeds it, and how many minutes it needs to go from 20 to 80% battery.
The rule fits in one sentence
TheOne delivers up to 65W. The wording matters: power is not imposed, it is negotiated. The device announces what it accepts, the charger matches it, and charging stops on its own when the battery is full.
That is what USB Power Delivery does. Wireless headphones will draw three watts, a laptop will take sixty — on the same charger, with nothing to set.
What 65W actually gives you
| Device | With TheOne |
|---|---|
| Smartphone | Fast charging, at full speed. Recent models draw between 20 and 45W. |
| Tablet | Fast charging. The hungriest ones reach about thirty watts. |
| 13″ ultraportable | Full charging at full speed. Their original brick is usually 30 to 65W. |
| 14″ laptop | Full charging. Shipped with 67 to 96W, they charge slightly slower on 65W — including while you work. |
| 16″ laptop or gaming PC | Top-up charging. These machines ask for 100W and more: the battery climbs, but slowly, and may drop under heavy use. |
| Headphones, watch, speaker, e-reader | Normal charging. The device takes only what it needs. |
If yours is not on the list
Two hundred devices are covered, not every one. Pick up the power brick that came with yours and read what is printed on it: you will find a wattage, or a voltage and a current — 20V and 3.25A make 65W.
Enter those two figures in the tool’s manual mode and it returns the same estimate. If that figure is 65W or less, TheOne replaces the brick entirely. If it is higher, it still charges, just more slowly.
Charging times, device by device
From 20 to 80% battery — the range where a battery fills quickly. The last column compares with the small charger most people already own.

Estimates, not measurements: they are computed from the battery capacity published by the manufacturer and the maximum power the device accepts over USB-C Power Delivery, with an average charging efficiency across the 20–80% range. Real times vary with temperature, the cable used, and whether the device is in use while charging.
Across the two hundred devices in the tool
100%
of phones, tablets and consoles receive every watt they accept. One hundred and seven devices, without a single exception.
88%
of the whole list is in that case. The rest still charge, simply capped at 65W.
14
devices out of two hundred ask for more under full load: gaming laptops and workstations. TheOne recharges those when idle.
Computed across the two hundred devices in the estimator above, from the maximum power each accepts over USB-C Power Delivery according to its manufacturer. It is the list that drives the tool — it was not assembled for the occasion.
About half an hour to go from 20 to 80% on a recent phone: 31 minutes for an iPhone 17 Pro Max, 27 for a Galaxy S25 Ultra, 28 for a Pixel 10 Pro XL. Roughly half the time a 20W charger needs. The tool at the top of this page works it out for two hundred devices.
It recharges one when it is off, asleep or lightly used. During a gaming session those machines draw more than 65W: the charger then slows the drain considerably without covering it. That is true of every 65W charger, whatever the brand.
Yes, a USB-C to USB-C cable rated for the power you want. A cheap cable will cap charging whatever the charger. The cable that came with your device works in almost every case.
They charge with the right cable on the device side and USB-C on the other. Charging works, at whatever speed the device allows.
Yes. Charging stops on its own once the battery is full, and a GaN charger draws very little when idle.
No, TheOne has a single USB-C port. That is deliberate: all the power for the device that is plugged in, in the smallest possible volume.
