Questions

Does the C4Plus need an app or Bluetooth pairing?

No. The C4Plus works straight out of the box — no app to download, nothing to pair. A BT 5.4 chipset is on board the platform, but the band is fully functional as a standalone device, which is exactly what makes it popular for giveaways and promotions.

How long does the battery last, and how do you charge it?

Up to 40 days of normal wear on a single charge. The main unit pops out of the silicone band and plugs directly into any USB-A port — no charging cable is needed.

Is the C4Plus waterproof?

It is daily waterproof: splashes, rain and hand-washing are fine. It is not rated for swimming, diving or hot showers.

What does the C4Plus track?

Accurate 3D step counting with steps, distance and calories on screen, plus time display and a silent vibrating alarm. It deliberately has no heart-rate or sleep sensors — if you need those, see the C1Plus, C2Plus or C3Plus in the same category.

Which colours are available, and can we customise them?

Black, sky blue, white and pink silicone bands. OEM/ODM customisation of strap colours, packaging and logo placement starts from 500 pcs per model.

Who is the C4Plus designed for?

Anyone who wants a watch-like time and activity display without a phone in the loop: retail promotions, corporate giveaways, kids and seniors, and entry-level private-label programmes.

What is the MOQ for the C4Plus?

Our standard OEM/ODM programme starts from 500 pcs per model, with mixed colourways available within one order.

How does the C4Plus differ from the C3Plus?

They share the same app-free LED platform — 17.2 mm band, 3D step counting, silent vibration alarm, 40-day battery and USB direct charging. The C4Plus is positioned around its four colourways (black, sky blue, white, pink); check each product's spec table for the fine differences.
