Comparison Gemei GM-250 vs MPM MMU-03

The purpose of this device is clear from the name: it is designed for convenient and safe cutting of lint from thin and rough-sensitive fabrics. Note that in some models, the nozzle for delicate fabrics is standard, and the possibility of installing other devices is not provided.

— Mains. Operated through a standard 230 V socket, this type of power supply offers nearly unlimited runtime due to constant network voltage. The only breaks needed are to change processed items and allow the device to rest. However, the limitation lies in the inability to operate without sockets and the restricted mobility imposed by the power cord. Consequently, this power supply method is rarely used on its own and is typically combined with battery functionality.

— Battery. Running on a standard, often built-in battery, this power source allows the remover's use without relying on nearby outlets. The absence of a network cable is an additional advantage. Although battery-powered devices are somewhat heavier and pricier than their network counterparts, the difference is minimal for lint removers and can't be considered a significant drawback. However, it's important to note that recharging the battery requires a power source, and the process is time-consuming once the charge is depleted. Additionally, battery-powered models are more costly than those with replaceable batteries. As a result, this option is relatively uncommon.

— Batteries. Operating on standard replaceable batteries, typically AA, though alternative options may be available. These batteries enable autonomous device functioning, with the advantage of swiftly replacing a depleted batte...ry with a fresh one. While battery-powered models are more affordable initially, they incur ongoing expenses as batteries need periodic replacement. Despite this cost, given the infrequent use of lint removers, it's not a significant concern, and the quick battery replacement feature proves beneficial. Additionally, rechargeable options are available, though they come at a higher upfront cost, eliminating the need for frequent battery purchases. For various reasons, batteries are considered the most convenient power source for lint removers.

The operating time of the battery-powered lint remover (see above) on a single battery charge. It should be noted that this parameter is quite approximate, because the actual operating time is highly dependent on the intensity of the load on the operating nozzle. In addition, manufacturers can indicate the battery life of the machine in different ways: some provide data at an average load, others at idle. However, this information makes it possible to assess the battery life of the device.

For models powered by batteries, this parameter is not indicated: different brands of batteries vary greatly in performance, so the actual operating time is determined primarily by the quality of the replaceable parts.

The time required to fully charge the battery (from zero to 100%) in properly powered lint removers (see above). This information allows you to estimate how long pauses in work will be required to charge the battery. (Although some models, supplemented by mains power, are able to work while charging).
