    £35 and a fortnight to ship from China, Amazon purchase. I've fancied a Biolite but the cost of one was daunting. I saw an unused Markill version on ebay but remembered Terry (Trojandog) had one, featured HERE so asked him how it served in the longer term - the fan packed up and he binned it.

    Packs up compactly.

    The powerhouse, a battery-powered centrifugal fan with a two-speed setting.

    A fair blast of air through the stainless steel pierced firebox base.

    Many of the posters of Youtube videos of this stove - and there are quite a few - overlook the rather vital detail of the air control shutter and keep it shut during the firing. Clearly, little or no air blast gets through to the firebox if the shutter's not opened. The combination of shutter and fan speed offer a wide range of control.

    Cover in place over the shutter.

    Collapsible fire box and pot rests.

    Pot rests swing out for larger pots.

    Everything packs away.

    The box and instructions.

    I'll be firing it up and featuring the results next opportunity I get - lots of heavy rain here for the past 48 hours.

    Hi John. It looks much better made than the Markill. On the Markill, the fan and electronics were cheap and flimsy, plus they were directly below the fire pot. In use, the bottom unit housing the fan, electrics and battery, could only be touched wearing gloves. Looking forward to your assessment of this gizmo.

    I wonder how it will run when the batteries are dead.

    With less vigour, Ken, as some of those U-tube posters had it performing by having the air intake flap closed. Just performs as a naturally-aspirated fire box.

    Taking along a couple of spare AA batteries wouldn't be too much of a problem, but I'll grant it gets away from the 'back to basics' aspect of burning found materials.

    I would wonder if the lack of a fan may conduct heat where it shouldn't be.

    It may well be ... all will be revealed when I fire this sucker up ... I know that's not how you speak Ken, it's received Americana from watching a couple of series of Bosch on Amazon Prime.

    Incredible detailed photo layout of every detail of the stoves. Post like this sure gives a real insight on a stove to decide if its for you or not as well as the ins and outs. Not my cup of tea but I if it landed in my lap it would be fun to play with.

    looks well made but i think the alloy parts look a bit brittle

    perhaps it is time for a brass revival - stove makers please note

    Once again .. Great Thanks John for another comprehensive/concise stove report.
    This thread and its extensions are, alone, worth the price of CCS full membership.
    The last pic of glowing embers is in a class of its own...quality above the already high benchmark you obviously set yourself. Quality.

    I'm very intrigued by this stove ... so much so I hit the BIN button and await the posty.
    The detail of the silicone seal/heat isolator and flip bottom and catch looks to be well thought out and neatly executed. Looking overall to be a well thought out package.
    6000 btu? with a 24kg load capacity..... that's serious overengineering.
    I've played with force air fed wood/charcoal stoves .... now realising the 'key' is a heat resistant 'fluid bed'.. as used in old/modern industrial boilers.
    A great post ,,, thanks for the dedication /time required. To my mind, a seriously interesting stove. Thanks for bringing it to my attention and it costing me ££s.. and an impatient long wait.

    Bloody stoves ,, b'strd pooters .. who'd 'av 'em ?
    Kindest regards, Nick

    Thanks Nick.

    I've PT'd you about meeting up for a test firing to tide you over while you're waiting to take delivery of yours.

    The development of the wood(gas) "camp"stoves have also/often been initated by needs in third-world countries. Open woodfires are still being used for cooking, and is a highly ineficcient use of a scarced supply of wood.Healthissues are also a concern, so are emmission into the invironment.

    Even those passive draught stoves offers a huge improvment in fuel efficiency and so adresses the issues above.

    These fan-assisted stoves further improves combustion and efficiency,and reduces polition both with regards to the households health and the environment. A way to power the fan is typically adressed with solar powered chargers.

    Stoves should be made avaliable at a low-profit policy in order to make them avaliable for these communities. Programs to support local manufacturing and trade should be encourraged.
