The 18650 3.7V 1200mAh Combo by Shektronix is a complete rechargeable battery kit that includes everything needed to power and safely charge a standard 18650 Li-ion cell. This pack contains one IMR 18650 3.7V 1200mAh 4.44Wh flat-top rechargeable cell, one durable 18650 battery holder, and one USB Type-C TP4056 1A charging module featuring smart auto cut-off and dual LED charge status indicators. This combo is built for users who want a simple plug-and-charge battery solution without compatibility concerns. The IMR chemistry cell falls under the high-drain category, which means it can deliver higher current when required while maintaining better thermal stability than standard low-drain cells. The included TP4056 module follows the safest 4.2V CC/CV lithium charging profile, ensuring efficient charging and automatic cutoff at full charge. The onboard LEDs provide clear status: red for charging and blue for fully charged, offering instant visual feedback. The 18650 holder keeps the battery removable and replaceable, enabling easy swapping without soldering. Spring-loaded contacts ensure firm grip and stable connection even after repeated use. The USB Type-C input allows charging using phone adapters, USB power sources, and power banks.
