Soldering

No 220V = no risk associated with the current.
30W: high power for a small device.
Unlike gas soldering irons, this does not involve any flame. Fire is not permitted in garages for obvious safety reasons.
No adjustment as with gas irons.
No ordering and shipping of gas (speaking logistically, shipping gas is problematic. e.g. by plane)
No cable. Very mobile with a high run time.
Precision tip for fine solders (connectors, etc.)
Universal tip for soldering cables (e.g: cabling a trailer hitch)
Tip for heat-shrink sheaths: Does not come into contact with the sheath so it doesn't melt it.
Its heating speed makes work easier: No need to heat the iron 10-15 minutes before starting work. Here it heats up in 10-15 SECONDS.
Case remains cold throughout the operation.
Warm-up time: 10-15 seconds
Runtime: 35 min real
Can also be used connected to the mains (charging)
Lithium Battery = 500-700 charge cycles
