First impression out of the box is the unit looks nice. I plugged it in and was surprised by the battery meter, and I also like that. I charged it, and decided to give it a test.First of all, it comes with a Presta adapter, and a needle for airing up sports balls. I wish the Presta adapter was attached somehow, because that is a part that will be easy to lose. It also has a little emergency flashlight built in. That could come in handy some day if you are out on a ride and get stuck with a flat as it is getting dark.Let me first say that this unit is not intuitive to use, and the instructions are not particularly enlightening. For example, the instructions say to set the PSI you want, and press the inflate button. Well, where IS the inflate button? Hint: it’s the power button. To power on, you hold the power button for a few seconds. You use the very lowermost button (with a M on it) to set the mode; they have city bike (58 PSI for some reason), road bike (100 PSI, which is correct), and manual (indicated by a gear icon) which you can use to set your desired PSI. If you don’t like PSI you can switch between BAR, KPA, and KG/CM if you are feeling a little European. You do that by holding down the mode (M) button.It seems like you have to connect the air hose to the valve first, and then set your desired air pressure. Once you have that set, wait for the display to return to 0.00, and then press power for just a second. The pump will begin inflating. It gets up to 50 or so pretty quickly, and then slows down. But it stops exactly where you set it, and I like that a lot. After airing up two tires from 0 PSI to 100 PSI the battery was still at 100%.It also seems like you have to screw the Presta adapter onto the valve first, and THEN screw the air hose onto that. I could not get it to work by connecting the adapter to the air hose first, and then connecting it to the valve. Doing it the first way worked every time.So, even though the instructions could be better, and the Presta adapter is finicky about what order it wants to be connected, these are not enough to take away a star. This is really a nice machine, and I will be taking it with me on rides starting now. If I could give it 4.5 stars I would, but I will not lower it to 4 stars.

We have more than a dozen road bikes scattered around our house and it can be a nuisance keeping air in all of those tires. I have several high quality floor pumps, also scattered around the house, but I also have a couple of battery-powered pumps than can take some of the drudgery of this task. This GPUTEK pump is actually the fourth battery-powered pump I have tried. The attached photo shows them, starting with this GPUTEK pump on the far left. Next is the first battery-powered pump I purchased and possibly the first of its kind; it cost $200 back in January of 2021. It works but gets very hot in use and can’t inflate many tires before the battery is discharged. I have used it for maintenance purposes at home but don’t take it on a ride because I don’t trust it as much as a frame pump since one sometimes gets multiple flats miles from home.The next pump I got, on the far right of the photo, is a piece of junk; it cannot inflate even a single tire before the battery dies. The one to its left works but the Presta adapter that came with it was just a standard Presta-to-Schrader adapter that did not function acceptably with the pump. I ended up buying a locking adapter (on a hose) similar to those on my floor and frame pumps to use with it. That adapter is shown in the photo attached to the GPUTEK pump. The GPUTEK’s Presta adapter looked like it might work as-is but leaked like a sieve on two different tubes. I tried tightening it enough to stop the leak but then could not remove it from the valve without using pliers and destroying it. Fortunately, my third-party Presta adapter works with it.With this third-party adapter, this pump is probably the best of the bunch. I was able to inflate ten tires, two of them to 100 PSI, and only lost ¼ of the battery energy. It did not get nearly as hot as the others and it could inflate the tires fairly quickly to about 50 PSI. After that it was significantly slower than a floor pump but perhaps still more convenient since you are just standing there holding it. It is rather heavy to take along on a lightweight road bike and we already have frame pumps on all of our bikes but it might make sense to bring it along if you have a heavier bike or perhaps as support for a group ride.

WHAT’S INCLUDED:PumpMain Pump HoseNozzle attachments (With Presta valve seals)USB Charging CableBike frame PouchInstructionsPRODUCT/THOUGHTS:This pump was exactly what I was looking for. I remember when we used to only have Co2 cartridges to fill our tires in an emergency, but now we have things like this. Rechargeable pumps.It’s very easy to use and operates much like any other portable electric tire pump. You have a couple of modes and you get both Schrader and Presta valve attachments. You get presta seals to use as well.There is a built-in light in case you need it. It’s not very bright but it has 3 light modes. 2 Blinking and 1 steady on. It’s better than nothing if you are in an area with no light and no other light sources.Everything fits inside the pouch it comes with and this pouch is made to velcro around your frame. But it can be a bit tough to get it tightened up enough around your frame or else it’ll just end up slipping upside down because of the weight. So I wish they improved this aspect. They did put some grip material on the pouch itself to help keep it in place but if they used a more “Cinch” Method for the tightening along with the velcro it would have worked better.If you’re an avid cyclist, you’ll appreciate this though. You can always toss this pump and accessories into your own bike pouch if you use one.
