Designed for 19L bottles. If you want to put on 5l, you will have to look for an adapter or (I made a hole in the lid from a 5l bottle, put it on the pump stem and filled it with a glue gun so that the pump did not hang out. Be sure to make an additional small hole for air in the lid or in the neck of the bottle, to compensate for pressure, otherwise, when the pump is running, the bottle will shrink due to the negative pressure inside).

Different pros: The battery lasts for a long time. This device has changed my life. I'm serious Has cons: I'm afraid my dog ​​will learn how to activate it soon☺

Different pros: pressed twice, - runs, clicked 1 time - stopped running, wow, technology Has cons: runs slowly, and with a small remaining amount of water in the bottle, it starts to pump water dying, it becomes a feeling that it is discharged.

With its pros: The pump works very well, convenient touch control. The charge is enough for a long time, not less than 8-10 bottles. Its cons: It is not clear what the scoreboard is for. It shows the speed of the engine

With its pros: Convenient touch control (quick double tap turns on the pump). Drains the water completely, nothing remains at the bottom of the bottle. Some cons: Slower than a hand pump. Does not stick to the neck of the bottle.

I made an adapter for 5 liter bottles. I am attaching a photo report. Algorithm: 1. We take 2 covers from 5 liters, we grind one by about 3 mm; 2. We make a hole with a diameter of 18 mm in each; 3. We bring one cover with a file to the point of putting it on the inside of the pump with effort; 4. We connect the covers together (glue, adhesive tape, etc.) There was no superglue at hand - I connected it with metallized adhesive tape; 5. We spill sealant on both sides; 6. Voila)

Some pros: Great stuff! I bought it for myself and bought it as a gift) the charge lasts for a long time Some cons: A little more power would be, but this is just a wish, not a drawback

It is important to keep in mind that it sits much stronger if you do not remove the cork from the bottle, but simply push the cap and lower the hose into the hole formed

Good pump, one charge is enough for 4-5 bottles stably, maybe more. The first start after a long idle double touch, which is great for safety.
