Gisam 400M/s Brushless Electric Blowers Jet Fan 300000RPM Handheld Leaf Turbo Blower Dust Blowing for Makita 18V Battery Pins

However, overheating issues appear with extended use. Several users report that at the highest power level, the motor overheats after 20 seconds to several minutes and the device automatically shuts off. Even at lower levels, continuous use longer than five minutes can cause overheating. Batteries drain quickly — with a 4 Ah battery, expect approximately three to fifty seconds of operation depending on the power level. The seller claims compatibility with Makita 18V batteries, but several buyers report that the batteries supplied in the set cannot be charged with a standard Makita charger.

Negative reviews (5.3% of ratings) point to battery and charging issues. Some users reported that batteries stopped charging or the device stopped working after a short time. One review mentions that a 5 Ah battery quickly enters safety mode and the device is practically unusable without larger batteries. The device is loud, especially at maximum power. Packaging from China was damaged in some cases.
