During colder months, a reliable heated vest or jacket isn’t just about comfort—it’s an essential companion for outdoor work, adventures, or daily commutes. InoKraft SWAP-ON heated apparel blends innovative technology with thoughtful design. To help your gear stay in top condition for seasons to come, we’ve put together this practical guide on how to properly wash, dry, store, and care for your garment—and its compatible 4V lithium battery.
Washing Instructions: Clean Safely, Protect the Heating Elements
-
Remove the battery and secure wiring
Before every wash, please fully detach the 4V rechargeable battery. Gently tuck the internal wiring into the designated inner pocket and zip it closed. This simple step is crucial to prevent moisture from reaching the electrical components and causing short circuits or damage. -
Machine washing (gentle cycle)
Your InoKraft heated vest or jacket is machine-washable on a gentle cycle—just ensure the water temperature stays below 104°F (40°C). For added protection of the heating panels and waterproof membrane, we highly recommend placing the garment in a mesh laundry bag before washing. -
Spot cleaning for everyday care
For minor stains, a damp cloth with plain water is often enough. Gently wipe or hand-rinse the affected area instead of washing the entire piece. Reducing full washes helps preserve the garment’s longevity.
Drying & Storage: Keep It Cool to Preserve Performance
-
Never use a dryer
The jacket features a TPU waterproof membrane that can warp or degrade under high heat. Please avoid tumble dryers, irons, and direct sunlight. -
Air-dry properly
After washing, hang your garment in a cool, well-ventilated area to air-dry completely before storing or wearing again. Any residual moisture could risk circuit damage or compromise heating performance—and even pose a safety concern. -
Recommended cleaning frequency
If you sweat heavily (e.g., during intense outdoor work), we suggest washing every two weeks to prevent salt and residue buildup that may corrode the heating elements. Always give your garment a thorough clean before seasonal storage to keep it fresh and ready for next use.
4V Lithium Battery Care: Safe, Efficient, Long-Lasting Power
-
Charging time & environment
At room temperature (~25°C / 77°F), using the original 1.5A charger, a full charge (0% → 100%) takes approximately 3 hours.
If charging exceeds 9 hours without completion, or if the indicator shows no change after 4 hours, please stop use and contact our support team at support@inokraft.com. -
Charging speed varies
Output ranges from 0.5A to 1.5A, depending on your charger and ambient temperature. Both very cold and very hot conditions can slow down charging. - Temperature guidelines
- Charging: Best between 32–113°F (0–45°C)
- Storage: Safe within 14–140°F (–10–60°C)
The SWAP-ON 4V lithium battery uses industrial-grade 21700 lithium cells, engineered for strong output and built-in safety. If storing your battery long-term, keep its charge level between 40%–60% and place it in a dry, cool location. This practice significantly extends its usable life.
