Kissmart Charging Case for Shokz OpenFit 2 / 2+ (T920 T921) — 500mAh USB‑C Replacement Case with LED Indicators

Compact replacement charging case designed to recharge Shokz OpenFit 2 (T920) and OpenFit 2+ (T921) earbuds on the go with a 500mAh battery and USB‑C input.

This Kissmart charging case is a third‑party power solution made specifically for Shokz OpenFit 2 and OpenFit 2+ headphones (models T920 and T921). It offers a 500mAh internal battery that restores multiple charges to the earbuds, a USB‑C charging port for faster wired topping up, and status LEDs that show charging and remaining capacity. Note that this case is not compatible with Shokz OpenFit T910, OpenFit Air T511, or other Shokz models.

How quickly will this case recharge my OpenFit 2 earbuds?

The Kissmart case refills the internal 500mAh battery in about 1.5 hours when connected to a 5V/0.4A source, and it can recharge the earbuds from empty in roughly 30 minutes. That makes it useful for short breaks and travel top-ups.

• Case capacity: 500mAh for multiple charges
• Case full charge time: ~1.5 hours (5V/0.4A input)
• Earbuds full charge time in case: ~0.5 hours
• Uses USB‑C wired input only (no wireless charging)

Will the LEDs tell me how much power is left?

Yes — the built‑in LED indicators give clear feedback while charging and during discharge. Open or close the lid to briefly view the status lights; they automatically switch off after a few seconds to conserve power.

• Red light: case is charging
• Green light: case fully charged
• During discharge: green = 20–100% capacity, orange = 0–20% capacity
• Lights remain on for about 5 seconds when the lid is opened

Is this charging case safe for my earbuds and what protections are included?

The Kissmart case includes electrical protections to guard the earbuds and case from common power problems. It’s intended solely for wired USB‑C charging and is built with safeguards for everyday use.

• Over‑charge protection prevents excessive charging once full
• Over‑current protection reduces risk from power surges
• Discharge protection helps maintain battery health during storage
• Not equipped for wireless or magnetic charging methods
