Kam Union Smart Ring Charging Case - Transparent Type-C

The KU-CB-H09A3 earns its place wherever Type-C leads are part of the day. At home, the phone charger by the bed refills the case overnight, and the ring charges inside it whenever it comes off. In the office, a laptop or desk charger tops the case up between meetings, so the ring goes back on charged for the journey home.

Travel suits it as well. A weekend bag usually holds a Type-C lead for a phone, and that lead refills the case in 1–1.5 hours, leaving one cable to pack for both. At 45.4 g and 50.4 × 48.4 × 23.7 mm, the case sits in a jacket pocket or the front compartment of a laptop bag.

Studios and employer wellness schemes are the natural group settings. When every member's case charges from the same connector, Type-C leads at a front desk or in an office drawer keep a whole group topped up, and staff can manage one cable type across the scheme. Members pick up a charged case at the start of a session, with the ring seated inside.

Retailers stocking smart rings get an accessory with a clear, everyday reason to buy it, because it refills from the cables customers use for their phones and laptops. Its 200 mAh lithium polymer battery and 30 mA output give the case a defined job: storing energy, then passing it to a ring at a low current.

Its users span office workers, commuters, weekend travellers, scheme members and studio staff who carry a Type-C lead for other devices. It fits naturally into any routine where a phone or laptop charger sits within reach.

Refills from the leads in daily use

The case recharges over Type-C, so the lead that charges a phone or laptop also refills it. Nothing extra goes into the bag.

A full case in 1–1.5 hours

Recharging takes 1–1.5 hours at 5 V and 200 mA, short enough to finish during a meeting or a meal.

200 mAh of lithium polymer storage

A built-in 200 mAh lithium polymer battery holds the energy that charges the ring away from a wall socket.

A low 30 mA charge for the ring

Output tops out at 30 mA, a gentle current for the small battery that sits inside a smart ring.

One connector across a group

When a studio or scheme issues this case, every unit runs from Type-C. A single cable type keeps the whole group charged and keeps spare leads simple.

Desk, bedside and car supplies

The 5 V input fits within the basic output of USB ports, wall chargers, and car adapters, so desks, bedsides, and car consoles all double as charging points.

A ring that shows through the shell

Transparent walls and a clear lid keep the seated ring visible, and a glance shows it settled in its tray.

Jacket-pocket proportions

At 50.4 × 48.4 × 23.7 mm and 45.4 g, the case slips into a jacket pocket, a handbag or the front of a laptop bag.

Charging where the ring is stored

Charging happens in the same tray that holds the ring between wears, so the case doubles as its everyday resting place.

5 V / 200 mA input

Its input is rated at 5 V and 200 mA.

30 mA maximum output

During charging, the ring receives up to 30 mA.

200 mAh lithium polymer battery

A 200 mAh lithium polymer cell supplies the energy for each ring charge.

1–1.5-hour charging time

From a 5 V supply, the case refills in 1–1.5 hours.

Octagonal transparent shell

The transparent shell takes an octagonal outline and keeps the seated ring in view.

White inner tray

Set inside the shell, a white tray forms the ring compartment.

Central charging post

A charging post at the centre of the tray, marked with a lightning symbol, holds the ring.

Clear lid

The clear lid closes over the tray while the ring charges.

One-ring compartment

The tray holds a single ring at a time.

50.4 × 48.4 × 23.7 mm body

Overall dimensions: 50.4 × 48.4 × 23.7 mm.

45.4 g weight

The complete case weighs 45.4 g.

Transparent and white finish

Transparent outer parts combine with a white interior in a single finish.

The KU-CB-H09A3 suits smart ring wearers whose days run on Type-C, from office workers and commuters to weekend travellers, as well as the studios, schemes, and retailers that supply them. Its strength is fitting into the charging routine already in place. The case refills from the same Type-C lead and 5 V supply that serve a phone or laptop, then charges the ring from its 200 mAh lithium polymer battery at up to 30 mA. Upkeep is a 1–1.5 hour recharge whenever a lead is to hand, and for a group, one connector type covers every case. In the hand, it is a 45.4 g transparent white case measuring 50.4 × 48.4 × 23.7 mm.
