From the reviews: "Excellent pump! Works with a 20 liter bottle. A very useful thing for summer cottages and outdoor trips. Available for children. I recommend!"
"Pump fire !!!Everything works fine, charges, pumps water. Of course, the performance is small, but more than enough for the home. Powered by an 18650 battery, easy to change in the event of failure, can be charged by regular charging from a smartphone or directly from a PC. I recommend buying ".
