Standard pocket power banks use raw, non-regulated circuits that experience rapid voltage drops when trail temperatures cool down past midnight. This fluctuating electrical current can damage the sensitive, microscopic lithium-ion cell cores inside expensive collars like Garmin or Fi, degrading their battery life over time. Furthermore, typical banks cannot be recharged effectively using solar panels once empty, leaving you with zero tracking utilities if your trip extends unexpectedly.

Most dog GPS tracking collars utilize micro batteries ranging from 250mAh to 500mAh capacity. Wawry's Micro 120W generator packs high-density storage capacity, allowing you to fully recharge a standard tracking collar **15 to 20+ times on a single charge**, ensuring complete security for your animal for weeks off-grid.

Wawry units are engineered with a durable, protective unibody shell that insulates the internal lithium cores from debris. However, to maintain safety during rainy or dusty trail conditions, we recommend charging your tracking collars inside your closed tent, vehicle trunk, or open backpack to keep active input vents clear of direct water contact.

Pure Sine Wave electricity refers to high-quality, ultra-stable current identical to the clean power supplied by your home wall outlets. Inexpensive alternative batteries use modified waves, which cause dangerous electrical interference and excess heat that can fry the delicate firmware or internal boards of tracking collars, satellite maps, and communication arrays. Wawry uses premium wave inverters to guarantee absolute component safety.
