What cold does to rubber
At low temperatures, rubber becomes harder and more elastic. A hard pad adapts less well to the surface, which can lead to leaks.
In winter, work with a slightly larger safety margin and check the vacuum before lifting particularly carefully. A pad that sits well in summer may adhere less well in winter.
Battery in winter
Lithium batteries lose power in cold. The runtime drops, and the pump can re-pump less often. Keep the battery warm, for example in your jacket pocket, until you need it.
Only charge batteries that have become cold once they have warmed up to room temperature.
Before use
Verdict
With a little more reserve and attention, suction lifters also work reliably in winter. Manual devices are often more robust in cold weather because there is no battery to be affected.
