  1. Outstanding! No go-bag is complete without one.
    Will the mega kit be available before the next disaster? :)

  2. Now all we need is a lipo charger built in. Maybe we can do a mega-minty board that has a 5V socket.

  3. Tell me if i’m wrong, but a couple of AA cells will provide around 3500mAh i think.

    Geekiness left apart, i’d prefer to take a "standard" minty boost with easily found 2xAA as replacement rather than this one with an expensive LiPo (which needs to be charged!)

  4. Have a solar/USB chargeable version of this ready to go. Waiting on a spiffy acrylic enclosure from ponoko. That lipo does take awhile to fully charge, but it sure can keep a USB chargeable gadget going for a long time! Will update forum thread with pics when assembled.

  5. I built a version of this that uses the usb/dc li-poly charger and is housed is a pepper can.

    It works awesome in that the spoon cover can fit both the usb A of the minty boost and dc/usb ports of the charger, covering them when not in use.

    I call it “Spicy Boost” with the tagline-“Put some pep back in your device!”

  6. Hi,

    here is my version of the ‘mega minty boost’.
    http://americanbikeadventure.co.uk/megamintyboost/megamintyboost.jpg
    it uses 2 sparkfun 5w solar panels (http://www.sparkfun.com/products/9241), a sparkfun 6Ah lipo battery (http://www.sparkfun.com/products/8484), a generic 12v to 5v car adapter feeding an Adafruit solar lipo charger which then goes into an Adafruit mintyboost – all contained in a small Otterbox.
    i use it on my bike when i am off touring. I carry a 9v wall psu to keep it charged up as well. it is used to charge up my homemade bike computer (this has its own lipo – http://www.sparkfun.com/products/8483 and charger), HTC desire, gopro and a couple of other mobiles.
    i will be adding a fuel guage sometime soon (http://www.sparkfun.com/products/10617) so my bike comp will be able to monitor charging.
    I will be putting up a project page for my bike computer and stuff, most of which is Adafruit / Sparkfun based, soon if you would be interested…
    many thanks for your excellent site and tutorials.
