Nice item, really good build quality. Fits my N95/KN95/FFP2 masks for mobile disinfection while driving. Even has a power switch. The interior is lined with reflective (hopefully also for UVC wavelengths) material, which greatly helps irradiating all sides of an item and boosts efficient use of the generated UVC. Yet, to reach effective sterilization, you still have to do multiple passes and flip the item to be treated in between for all sides to be sufficiently irradiated, or use much longer treatment times from one side and rely on the little transparency of a mask. The bag adopts a low pressure mercury tube as UV source, not some weak or fake LEDs. Effective length of the lamp is about 8cm, and it draws about 800mA (4 Watts) from the USB power supply. You can expect between 0.5 and 1 Watt of UVC from it (depending on the efficiency of the integral inverter/driver circuit). ("Cheap" UVC LEDs currently often offered only deliver around 0.005W of UVC each!) However, lke fluorescent lamps, once turned on this bag's UVC tube needs a minute or two to warm up and reach full brightness. I am pleased with both the bag and the price I paid.

The bag fulfills everything I expected of it, solidly done, functional

Taška splŇuje vše co jsem od ní čekal, bytelně udělná, funkčí
