Mecha Transparent 8 Slot 21700 Battery Case Kit Type C

Step into precision power with a Mecha Transparent 8-Slot 21700 Battery Case Kit Type-C, a modular, high‑performance power hub you can see and trust.

• Mecha transparent design reveals the internal layout while holding eight 21700 flat batteries, giving you a clear view of cell arrangement and wiring for confident builds.
• Fast charging power: 22.5W integrated PD/flash charging with Type-C output at 5V/3A, 9V/2A, 12V/1.5A to top up devices quickly.
• Welding-free modular construction makes assembly simple without soldering, and a protective spring prevents reverse-install damage to the motherboard.
• Safety and compatibility: built-in overcharge, overdischarge, and short‑circuit protection; supports 21700 flat cells in 3.5–4.2V range with real capacity ≥10,000 mAh; if fast charge isn’t supported, PD output remains the most stable option.
