Is there a truly portable electric battery operated bicycle (presta) pump?

There are a couple of full sized options: extremely popular and well priced Xiaomi Mijia digital tire inflator, a ridicuolously overpriced and still bulky Fumpa.

Is there a truly portable and Presta valve optimized emergency pump for road punctures?

Portable hand pumps are a compact option but they may damage the valve. CO2 are great and compact but destroy the tyre sealant.

I need something really small and it is enough for it to be able to inflate one bicycle tyre to 35-45 psi after I install the tyre "worm".

PS Upon further discussion and internet searches I am going to use Mini or Nano Fumpa.

    This
    looks to be as small as they get.
    As long as you have a portable pump with a flexible hose and aren't overly rigorous on the pumping action the valve should be fine i've done it for years and haven't damaged a valve once.

      It appears the technology is not there yet. 465 grams! Ouch

        i know you bike riders dont lift but 465 grams br0

        stop the legs days and start on the guns br0 the GUNS

          Haha very funny. My lifting abilities may be limited, but I can lift 465 grams just fine. The problem is where I have to carry an extra 465 grams daily in my backpack together with everything else for years and thousands and thousands of kms.
          In cycling world to lose 465 grams of your bicycle will probably cost you somewhere around $1-2k depending on the bike level and other variables.
          Also, if we compare this to 65 grams of a hand pump and 20-30 grams of a CO2 system… That's a 10 times difference.

      Yep, over decades and several bikes I've never damaged a valve using a hand pump so this isn't even a concern IMO. OP, I assume when you say portable you're looking for something to cycle with because there are a heap of options that are portable?

      • Musiclover on 09/02/2022 - 13:12

        Correct, something to go in my commuting bag.

        • apsilon on 09/02/2022 - 14:34

          IMO don't waste your time even looking, stick with a mini hand pump. You can get some nice ones that work like a floor pump.

      Same here. I have one of the small ones that I have clamped to the frame. Been riding for decades and admittedly, I don't use the "portable" pump all the time as that's only for use while being on the road. However, I have used it a fair a number of times and it attaches to my valve the same way my shop pump does. Never had and valve damage from using a pump before.

  • Catullus on 09/02/2022 - 13:52

    Used to be a little hand pump, about 20 cm long, no connection, straight on the valve.

    Let me get this right….You want something electric, containing a battery and compressor to weigh the same as a small, manual pump?

    A small pump will do the trick, plus get one with a house. I have a very small pump that has foot levers folded into it so it can be converted to a mini floor pump.

    Carry a spare presta valve if required - simply remove the core and replace. Takes only a few seconds to change - I do this sometimes if the tyre sealant has seized up the core's threads etc.

    Just get a mini hand pump. You aren’t even getting to high pressure.

    Alternatively, use CO2 while out and about but replace it with air from a track pump to compressor when you get home.

    IMO a mini electric pump is a great thing for adding weight to your kit AND increasing the chance of failure when you need it most.

    • Musiclover on 09/02/2022 - 15:41

      Obviously, electric pump is less reliable than a hand pump, I do not see why it would necessarily fail on a rare occasion when you need to use it. In terms of weight though, mini and nano fumpa are very competitve (I would say their weight is comparable to hand pumps, not 645 grams). Nano is 100 grams.

        Part of the problem with a rarely used item is it being more likely to has problems due to not being used. Batteries die, seals dry out etc. sure, same can be said for a rarely used mini hand pump, but there is much less to go wrong.

        • Musiclover on 09/02/2022 - 18:08

          Lithium batteries can usually take around 300 cycles before their capacity will start to decrease. Maybe another 300 before it dies (decreases to zero). If there is no self discharge I just don't see how it will die within any reasonable time. Since a puncture which is unable to be sealed with a tyre sealant happens to me around every 4000 kms, all I need to do is to check that it is still working say every three months. I am yet too see a pump which seals died so that it is unable to be used, but since it is not specific to an electric pump we can just disregard that.
          I do not argue with you, but how am I increasing my chances for a pump to fail by using electrical one?.. I am just not convinced. I think I will take my chances.

          • Euphemistic on 09/02/2022 - 19:44

            @Musiclover: Electronics have a habit of just packing it in. Vibration, heat, moisture are some of the contributing factors. Making stuff as light as possible while also being cost effective also contributes to reduced longevity.

            I have no doubt that these little compressors work. I just wouldn’t risk it when a hand pump or co2 will do the job more reliably.

            To each their own though.

    Since the 465g Aliexpress pump (as discussed above) seems to be "too heavy" for your liking then you always have this option
