In many reviews should be noted that wood every few minutes refills. Thanks to some US reviews I've tried times pellets. With a refill of pellets (400g) I had 45 minutes full combustion performance. After the flame has gone down slightly and turned blue - mobile phone recharge was still and hot move to such as sauces, it would certainly rich, but boil 1L water was no longer (smaller amount might) but for grilling would have probably have to replenish at 45 min. After 1.5h embers was still in there and invite phone also went.
With wood pellets is therefore likely the best focal power / volume have money, do not smoke and it can be planned a little better, how much you must take. And if that's not enough, you can then still collect fuel go (as opposed to gas cookers;)).
I also recommend the Biolite Kettlepot - although is very expensive for a water pot, but the water is boiling, thanks to the building very quickly and the whole thing still act as a receptacle for the Biolite itself.
The griddle plate for I will still test - fits ever good to Biolite on it, but the self-test is still pending. Will write about ...
Supplement May 2015. First Camping use mastered well. Somewhat annoying only that the fan for some reason the "cheering" always starts after a few minutes (probably because it is not hot enough and the unit "thinks" it is in the cooling phase). Ie Initially it is essential to constantly take care of the fans, but when it is in full läufts first and tidy. Cook pasta or water has everything just fine and admiring glances gave it too;) mobile phone charging function rather so-so, but that is rather trivial. Fun with the thing! :) (Griddle plate has not been tested yet ... comes)
