Wearfit Pro watches charge on small magnetic cables and docks shaped for one model, so the watch's own name matters more than the app it pairs with. Match the charger, keep the contacts clean, and change the strap by its width.
Refreshed September 2026Identify the model first, because the charger follows the watch and not the app. Then replace or double up on the charger, clean the contacts, and only after that play with straps.
A magnetic dock on a 30cm USB lead, made for the HW22, that holds the watch upright while it fills. Keep one on the nightstand and one in the desk drawer, and the watch never waits for its cable.
Have a lookWearfit Pro is a phone app, and the watches that pair with it come from many different factories. Each factory shapes its own charging contacts, so the magnetic puck that fits one watch can sit uselessly on the back of the next.
That makes the model name the only safe guide. A charger sold for the HW22 fits the HW22; a watch from AOC or Yihou uses the cable that came in its box. Pairing with the same app says nothing about sharing a charger.
The HW22 magnetic dock is the replacement to reach for when an HW22 charger goes missing. It is a small stand rather than a flat puck, so the watch sits upright on the nightstand and the time stays readable while it charges.
The AOC E07, AOC Z17 and Yihou AW83 each ship with a charging cable, and that cable is the one to keep safe. The E07 also has a spare made for it: Lamshaw's charging cable, with a USB-A or USB-C plug. Treat it like a house key: one spot at home, never loose in a gym bag.
A stretchy braided nylon solo loop with quick-release pins, made in widths from 16mm to 24mm. The 22mm suits the AOC E07, the 20mm the round Z17, and the soft weave stays comfortable through a night of sleep tracking.
Have a look
All three Wearfit Pro watches carry a 300mAh battery, and a steady habit keeps each of them on the wrist for days at a time. The routine takes less time than choosing a watch face.
The AOC E07 and Z17 each reach full in about 60 minutes. The Yihou AW83 needs about two hours. The E07 is rated for up to 10 days on a charge in silver, 7 days in white; the Z17 and AW83 for up to 7 days.
Those are best-case figures. Frequent calls on the wrist, a bright AMOLED screen, all-day heart rate and the voice assistant all drain the battery faster.
Turning the brightness down one step and shortening the screen timeout buys back noticeable hours. The watch manual shows where both settings live.
A Wearfit Pro watch that refuses to charge is rarely broken. Most of the time the contacts are dirty, the charger sits crooked, or the USB port is not giving power.
Work through the easy causes in order, from the charger end to the watch:
Green or white crust on the contacts means corrosion. A little isopropyl alcohol and a soft toothbrush usually lift it; let everything dry fully before the next charge.
| What you see | Likely cause | First fix |
|---|---|---|
| No icon at all | Dirty or misaligned contacts | Clean and reseat |
| Icon flickers on and off | Loose magnet contact or tired lead | Reseat, then try the spare charger |
| Icon shows, battery never climbs | Weak power source | Another USB port or adapter |
| Charges only at one angle | Worn charger | Replace the charger |
If a clean watch still ignores a second, known-good charger, the fault is inside the watch. That is warranty territory.
| Watch | Charger | Full charge | Strap width |
|---|---|---|---|
| AOC E07 | Cable in the box; Lamshaw spare | About 60 minutes | 22mm |
| AOC Z17 | Charging cable in the box | About 60 minutes | 20mm |
| Yihou AW83 | Charging cable in the box | About 2 hours | Measure the strap end |
| Dibymar Elegant | Charging cable in the box | About 2.5 hours | 20mm (0.79in) |
| HW22 | HW22 magnetic dock, 30cm USB lead | Varies with battery wear | Measure the strap end |
Charge times and strap widths as each maker states them. A charger made for one model does not carry over to another, even when both pair with Wearfit Pro.
A Wearfit Pro watch that stays dark after a long week without its charger is usually just deeply flat. A drained battery needs time on the charger before the side button responds at all.
Give it a proper chance before deciding anything is wrong:
A watch that shows the charging icon but will not start usually needs a longer charge. Leave it for the full charge time, about an hour for the AOC watches and two for the AW83, then try again.
A frozen screen is a different problem. If the face is stuck on one image and ignores every swipe, a long press on the side button often forces a restart; a battery left to run out does the same, more slowly.
One habit prevents most of these scares: never store a watch flat. A watch left in a drawer for months drains to zero, and a battery kept empty for long ages faster. Top it up to about half before it goes away, and charge it again every few weeks.
A new strap is the quickest way to make one Wearfit Pro watch look like three. The AOC E07 takes a 22mm band and the round AOC Z17 a 20mm one, and both ship with two silicone straps in the box.
Quick-release straps need no tools. Each end carries a spring bar with a tiny lever; slide the lever, the bar retracts, and the strap drops out. The new one clicks in the same way.
E07 owners who prefer a strap made for their watch by name can turn to FoundEast's E07 bands, cut in silicone, two-tone silicone, leather, stainless steel and a soft loop.
For a watch without a stated width, such as the Yihou AW83 or an HW22, measure across the strap end where it meets the case. The number in millimetres is the width to buy.
Pair the strap with the dial for the full effect: a rose or white face next to a pale loop, a bold dark face on black. The watch faces how-to shows how to put your own photo on the screen to finish the look.
The watch needs its own magnetic cable or dock, but the USB end of that cable plugs into a phone adapter or a laptop port. The phone's own charging lead does not fit the watch.
It is made for the HW22. Other Wearfit Pro watches use contacts of a different shape and spacing, so they need the charger made for their own model. For the AOC E07, Lamshaw makes a spare cable of its own.
The AOC E07 and Z17 each take about 60 minutes to fill; the Yihou AW83 about two hours.
Most often the contacts are dirty or the watch sits crooked on the charger. Wipe both sets of pins, reseat the watch, and try another USB port before suspecting the battery.
A deeply drained battery needs at least 30 minutes on the charger before the button responds. Then hold the side button for three to five seconds.
The AOC E07 takes 22mm and the AOC Z17 20mm. For other models, measure across the strap where it meets the case.
