CHANCS USB-1020 Lift 200L/H DC Mini Submersible Water Pump 3.5-9V with USB for USB Power

Purchased for my water feature an it works perfectly well, would highly recommend

Pump is fine, used to replace an existing pump which had worn out its nylon impeller bearing after about 8 seasons use, the original pump had a detachable filter chamber with a coarse sponge filter, this was invaluable as it stopped any detritus in the water (dead insects, grass clippings, decaying leaves, algae, etc) from entering and jamming the pump, if the flow slowed, I'd just unclip the filter housing and flush the filter out, and clip it back on, there's no filter on this pump, just a slotted base (which unclips and has a sliding plate to adjust flow), but I doubt it'd stop the smaller stuff getting sucked in, as a temporary fix I used insulation tape wrapped around the base and a chunk of coarse aquarium filter foam to form an inch long tube with an open end that holds the foam in place, I keep looking for something that I could adapt to form a better chamber for the filter and seal against the base of the pump, but no luck so far, it's a minor gripe and it's a cheap enough pump, I was half tempted to just transfer the impeller from the new pump to the old (assuming dimensions were similar)

I have this connected to a 12v battery and a solar charger, as soon as the battery reaches 12v the pump stops, it won’t restart unless I remove it and turn the impeller. I have had it about 3 months and now it does not lift water 12” let alone 1.5m. It’s cheap but rubbish.

This was not compatible with my solar panel so had to return it

It’s a bit hit and miss working buts does go when the sun is strong.

The old one in my water feature had packed up so I took a chance and ordered this one, even though it was smaller in size. My fountain is now working perfectly again.

For being cheap it has been perfect so far can imagine it wont last forever but i may be wrong. Does what it says and it good for the price

I bought this based on flow rate and head height. The two main aspects you would buy a pump for right? This is marked as a 0.4 to 1.5mtr head height max and flow rate of 200ltr/hr. What it actually does is less than 0.4 head height and a variable flow rate.

Remplacement, à l'identique, d'une pompe qui fonctionnait depuis plusieurs années.

庭に昔実家で使っていった火鉢を土中に半分埋め込みそこに水を溜メダカを飼っています。ここにソーラー発電装置からのDC12V電源を利用してこのポンプを使い手製濾過装置の水をくみ上げ濾過をして水を循環させています。音も静かで汲み上げ力も強く大満足しています。

Pas compatible avec ma fontaine

メダカの水槽用に使用しています。桶で飼っているので水を掻き回してやると流れに逆らって川の中の様に泳いでいます。

Tout petit débit mai parfait pour ce que je veux en faire, ne consomme rien, j'en suis contente
