Gisam 400M/S 3000W High Power Brushless Turbo Fan Electric Air Blowers Jet Fan Snow Leaf Dust Tool For Makita Battery Pin

The blower has three power levels. On the first level it achieves approximately 700 g of thrust, on the second around 1.2 kg, and on the third up to 2 kg — figures that buyers have verified on kitchen scales. A 6 Ah battery lasted around 35 minutes of continuous use. The device is lightweight and comfortable to hold, but on the third level it requires a powerful battery (at least 4.5 Ah), otherwise it shuts off. The package often includes two batteries and a charger, which buyers consider a major advantage.

The main drawback is noise — the blower is very loud even on lower settings and requires hearing protection. The second issue is power consumption: on the third level it draws 60–80 A, meaning weaker batteries drain quickly or the device cuts out. Some users also noticed the motor heats up after one minute at full power and needs cooling breaks. The plastic tube is difficult to disassemble after assembly. One buyer mentioned the blower shuts off after one minute at maximum power if you don't remove and reinsert the battery — though this problem appeared only in isolated cases.
