Sorted by capacity per battery. Identical devices appear only once.
This ranking sorts electric vacuum lifters by the capacity per battery in milliampere-hours (mAh). Across all battery gripsters, the typical value is 3,000 mAh.
How to read this ranking
The figure counts a single battery. If a second battery is included, the available energy doubles, but the ranking shows the value per battery. Built-in batteries typically state 4,000 mAh, removable batteries typically 2,400 mAh.
What to watch out for
mAh figures are only comparable at the same voltage. Energy in watt-hours is more meaningful: an 18-volt battery with 2,000 mAh stores 36 Wh, while a 3.7-volt battery with 4,000 mAh stores just under 15 Wh. The actual runtime of a gripster also depends on how often the pump has to top up the vacuum. More in Battery and charging and in the comparison Removable battery vs. USB-C.
