Lenz Lithium Pack RCB 2000 (USB-C)
Smart, all-day warmth—head to toe.
The Lenz rcB 2000 lithium packs are the heart of the Lenz Body Heat System, delivering reliable warmth from your socks to your jacket. Compact, lightweight, and powerful, these rechargeable packs clip in easily via push buttons and provide up to 22 hours of consistent heat for work, sport, or everyday cold-weather missions.
Control the heat directly on the battery (three levels) or fine-tune it on your phone with the Lenz Heat App for stepless temperature control—perfect when the packs are buried under layers. The included charging cradle doubles as a transport case and offers both fast-charging and storage modes to keep your batteries healthy for the long run.
Stay warm, keep blood flowing, and perform at your best—no matter how deep winter gets.
