The hot water bag contains clean tap water and is well sealed. You don't need to inject water every time when you use it, just plug in the charger to heat it up.
The hot water bag contains Edon's patented double-layer insulated silica gel heating wire, which separates water and electricity, equalizes the heat, and is safer and quieter to use.
The inner tank has 6 layers of environmentally-friendly thickened PVC, which can withstand pressure up to 80kg.
This hot water bag and hand warmer cover are connected together, which is easy to use, and you can warm your hands directly after charging. But the cover is not removable. Usually need to pay attention to maintenance.
Here is empty.
