Summary: This is a lithium battery powered vacuum cleaner ideal for small/quick jobs. collapsed. The lid protects the dusty end during storage. The extension cord and brush work well, the brush is good for cleaning the keyboard. USB-C charging port/cable. The battery consists of three cells connected in series, so the total capacity is 2000 mAh at a voltage of 11.1 volts. The 3-level charge indicator tells you when to charge. Recommendations: 1) Lithium batteries last longest at 30-50% charge, so it is best to use, then store and recharge before next use; This is less of a problem with USB-C because it charges faster. 2) The paper filter is quite small, so you need to keep it clean carefully to keep the suction power. I plan on draining and cleaning after every few uses. Advantages: lithium battery; extensions included; force meter. Cons: The filter is quite small, it will be a clogging point. Conclusion: For 44€ there are 5 stars. If you also need a powered (compressed air) solution, I can recommend the product below, which is in a different category (the 2-in-1, just the vacuum): 1, $100 https://www.amazon. com/gp/product/B08CVH5XLT
