This is the replacement charging case from the Hollyland LARK M2 Combo wireless microphone kit, in the Shine Charcoal finish. The LARK M2 is a compact 2.4 GHz wireless lavalier system for content creators, vloggers, mobile journalists and videographers, and the charging case stores and charges the tiny clip-on transmitters and receiver when they are not in use, doubling as a protective carry case. Hollyland states that the Combo version ships with the camera-version charging case, which has a 1,950 mAh built-in battery, recharges in under two hours via USB-C and can recharge all of the transmitters and the receiver at the same time more than three times. Combined with the transmitters' roughly ten hours of runtime per charge, that gives around 40 hours of total recording time away from a power outlet. The case measures about 86 x 54 x 39 mm and weighs approximately 111 g. It is a spare part for existing LARK M2 users who have lost or damaged their case: transmitters, receivers and cables are not included.
