Portable USB Camping Fire Charger, Red/Grey/Black

Great product. Every now and then, someone comes up with an amazing idea - this is it. It is lightweight, functions exactly as described and does the job - you can now charge your cell phone or any USB small device without solar. I tried it using the included instructions, and it began charging my Samsung cell phone. Yes, it takes time, but this is a smart addition to a backpack, especially in areas where it rains a lot or snows. It folds up and takes up very little space. Highly recommended.

Needs to mention it has a 3 VOLT MAX OUTPUT. So yes it works with many devices, but if yours needs more than 3 volts to charge this item will not do it. I like it but one of the items I wanted to charge needs more than 3 volts output (input to device) to charge. Would also believe a little longer on the heat plate, I have 4 more inches it could have been to fill the width of my backpack. Yes small and compact but only usable with a stove due to the length of the heating element. Picture one is what it did when plugged in, but that is all it ever did - gained no charge on that device. And it was "flashing" which I would call "pulsing" to be more grammatically correct.Fortunately it was sunny (partly cloudy) so I used the backpacker solar panel I had and that was able to fully charge the phone - it has a 5 volt output.

Manufacturer states this: Electrical: 5V, 2.5W PeakI do not know what the Peak means, or under what conditions they may have achieved that.The fact is that I plugged my HTC Desire into this and let it go for an hour. I did not gain a single percentage point on my battery.NO CHARGE WHATSOEVER.Seemed like a great idea, I build a fire almost every day.I am thruhiking the Appalachian Trail and am a serious gear head. Anything I can do to make my life easier, I will do.This is not one of those things, it's just another instance of a bad design being pushed thr the system by faked reviews. Seriously, get a real product guys, one that actually does what it says it will do.

Second star is just for having a pretty good idea. The implementation however is definitely not ready for primetime. I used this with a Solo Stove (check those out if you haven't because they are amazing) and was barely able to get any current draw despite a massive temp differential. Even if it had achieved what it claimed, the amount of power needed by modern phones, gps units, and the likes exceeds 5W (way beyond this things 3W if it ever achieves that.) That standard by the way has been true since at least the original iPhone from 2007!!!Other problems include statement about not letting the device get soaked with water. Well they put a water well on top for cooling so how much foresight does it take to see danger on the horizon for your product. Also, even setting that aside for a moment, this is supposed to be used outdoors. Now I was Silicon Valley coder/engineer myself once so I realize none there has ever seen a rainy campsite. Take it from those of us who have camped or hiked in other parts of the US (and I imagine even more so outside the US), wet outdoors makes components impossible to keep dry or clean. So put some freakin' epoxy over the sensitive parts already!!!

Although I really wanted to like this device upon use I find that is very slow to charge anything at all. so in an absolute emergency it would be useful as long as you have a plentiful fuel supply. It barely achieved a one watt charging rate on my gas stove so don't expect rapid charges. This versus my solar panel which easily achieves a 5 W charging rate.

Just a little pricey, but a need is a need. Everyone should have this, its a necessary product for campers and preppers alike. Its awesome.

bought this as a gift. the happy couple have been able to use it this winter/spring and report its "rad".

It does what it says it does. It produces electricity and can charge stuff. I used this in conjunction with my biolite stove to cook a meal. On a typical meal I can probably get anywhere between 5-10% charge on my Sony Xperia Z3 compact D5803. However the flame stower only was able to charge it 3-5%.. BUT it is about half the size of the biolite. I am not sure how heavy it is, but it is heavier than I had expected.I would say it is better than nothing though! I definitely think it is worth the money if you already have a stove.
