Mini Emergency Water Pump (1000ml/min) Compatible with Membrane Sawyer LifeStraw Personal Water Filter for Hiking, Built-in 2000mAh Power Bank, 3-Speed Adjustable Flashlight & SOS Signal Light, IPX3

Replaces water bag in a Sawyer gravity system. Works great (so much faster) and a tenth of the trouble. Wish I had found it earlier and really hope it continues to work!

To those that haven't read the product description carefully, this is NOT a water filter! It requires a water filter like a LifeStraw or other brand. The job of this product is to serve as a water pump for those smaller "straw" purifiers. I was surprised at the decent water output this provides.Its case is a little cheap, and I'm concerned about getting replacement connectors to attach the straw if they break, but it works well and doesn't cost much. The instructions are a bit baffling due to the poor English, but it's easy enough to figure out. I wish these companies would invest a little into having instructions written that actually make sense!One thing to note is that this will not charge--not even try to charge--using a standard USB-C PD charger. You need an older power block with USB-A, probably something that supports QC or older protocols. Maybe a give-away that they supply only a USB-A to USB-C cable.It's good for what it is and for what you pay. If I get a lot of use out of it, I will pursue something of higher quality, but for now I want to see how useful I find it to be. As far as the light goes--eh. Not what I bought it for.

Just tested it out today with my lifestraw and was surprise how well it worked. I also like the additional features such as the flash light and usb phone charging abilities. It looks like you can take out the rechargeable battery as well. I may purchase another.

Received product turned it on for 10 secs to make sure lights and pump worked. Then turned it off because battery indicator said it was drained. Used charger sent with it and tried to charge it. It never came back on. Not even going to try to get a replacement. Just cutting my loses and getting something higher quality.

If the grid goes down, you’ll want two of these for your straw style filter! The time and energy of pumping through a sawyer mini bag isn’t worth it, just buy this pump. The silver is all plastic but it is light weight so you can pack it for backpacking and camping. It can be recharged via USB via Solar panel or battery and had a flashlight.

The easiest way to use your water filter or gravity for the flow and super lightweight ease to clean!!!

bought this to take on a camping trip to the local lake. I stayed for 6 days and always had fresh clean water to drink and cook with. I used a LifeStraw as the filter and was able to fill a 2 gallon jug in under 11 mins. To me this was money well spent.

We bought a second pump as a back Up - good thing as the first one quit working after 6 months. We do use it regularly as we filter all our drinking water - about 1 gallon a day. We will need to find something more dependable in the long term.
