Rechargeable warmers (or electric warmers or rechargeable pocket heaters) are a great supplement to your sleeping bag or blankets when keeping warm at night. They are pocket-size power banks with a built-in resistance heating wire so you can warm up when needed and later plug them in to recharge when power is available. These are an alternative to chemical warmers or hot water bottles if you have a reliable way to recharge them.
Non-electric warmers such as this Zippo lighter hand warmer may help if you don't have many places to recharge devices.
- If you drive a lot, you can recharge while driving.
- If you have a job, plug them in at work.
- If you have an electrical system with solar panels, you can recharge them during the day as needed.
