What it does
The SP-03 Water Pump, in three points
One adapter, four bottle sizes
The adapter fits the pump to bottles from 1 to 5 gallons, so one pump serves the big jug and the small one.
A wider tube
The silicone tube is 0.67 in across. Water meets less resistance, and the pump moves 4,000 ml a minute.
It folds
Bend the tube to pack it. It springs back and the flow stays the same, so a kink does not end the trip.

In use
At home it works like the SP-02: head on the neck, tube to the bottom, one press. On the road the tube folds into a bag and the same pump moves from the big jug to a one-gallon bottle.
Check before you buy
- Your bottles are between 1 and 5 gallons
- You keep the adapter with the pump when you travel
- You rinse the tube after juice or flavored water
Pick another one if
You only ever use 3 and 5 gallon jugs and want a color choice. The SP-02 comes in black, mint and white.
From buyers
What buyers say about the SP-03 Water Pump
Quiet and Efficient
So far I've been very impressed with this water pump. Someone else's review has a video of the same one I used to have (grey and pink) that got SO noisy! This one is quiet and pumps out the water super fast. It also came full charged and I've only had to charge it once after a long time, and we use it daily so the battery charge is long lasting. Haven't had to clean it yet so I'm not sure how annoying that might be. Super easy to use though and fits on my 5 gallon perfectly.Someone was saying how the hose wasn't long enough - I will say I was concerned about that at first too. The tube takes time to fully straighten out and get long enough to reach the bottom of the 5 gallon but it eventually did and I have no issues with the length any longer.
Doesn't fit a standard five gallon jug.
Do not buy. Doesn't fit a standard five gallon jug. Marketing for this product is a lie. Doesn't work for five gallon. Also, cheap product for over $50. Less expensive items work much better. Appears nice in photo, but when purchased you'll realize it's super cheap quality.
Very fast, very quiet.
This water bottle pump has worked very well for me. It fills up a 16oz cup very quickly so you have to watch it or it'll over fill your cup. Some people complain about how noisy some of these type pumps are. I can't compare the noise level of the pump because I don't have another brand for a comparison, but I find it very quiet. Also, it comes with a universal adapter that fits on all different types of large water bottles. I use a bottle that has a screw cap. The adapter fits perfectly. About the only negative thing I can say is it's on the expensive side compared to other brands, but I'm still quite happy with it.
Great little pump
I don't love the price, but I really needed a pump that was not manual with good flow. This pump is GREAT!! Operation is quiet and puts out a good amount of water quickly. Also shuts off as soon as you hit the button to stop it with no drips. I am planning to buy a second one to have on hand in case something ever happens to this one.

Questions
SP-03 Water Pump: answers
What is in the box?
The pump head, the folding silicone tube, the bottle adapter, a USB-C cable and a user manual.
Is the SP-03 quieter than the SP-02?
Both keep the motor under water at the end of the tube. In a quiet room you hear the water more than the pump.
Can I use it for anything but water?
It is built for drinking water. For milk and juice in the fridge, use the Milk & Drink Dispenser.
