When they do not put the full spec you do have to wonder why they are withholding that info, where is the power output rating or even an estimate on charging its internal battery from flat?
fleck2, re: your link to the 20,000 mAh powerbank, it just wont LOL.
Its more likely to be 2000mAh or 4000mAh at best.
I have an LED torch and it came with some free batteries and a mains charger, the charger was a fire risk and got binned.
The batteries are labelled 6000mAh, i was expecting 600, but it seems like i got some good ones and it charges to around 1200mAh, nowhere near the 6000 they claim to be.
From the dimensions it seems like the unit in your link is a 4 or 5 cell unit, My guess is its 4000mAh.
I got this emai from them the other day.
"The TEG produces 5 volts at 1amp, this is more than the iphone 6 can consume as the charge rate of the phone is between 800 and 900 milliamps. The stove has a 3000 mA battery so when you are not charging a device - but the stove is on, all the energy is stored in the battery for later use, you can charge the internal battery before going off grid if you want to via the micro USB port.
To give you an idea of the charge rate, twenty minutes of burner run time will equate to approximately 25% charge of an iPhone.
The cost saving comes from the use of Butane, Butane gets cold and fails to turn into a vapour (no gas pressure), this is why people will pay three times more for a mixed gases that don’t suffer in the same way.
Tegstove makes Butane work (no pressure reduction) and this reduces running costs (mixed gas £4.50 butane £1.50) so after using just ten gas cylinders you have saved £30, One standard butane cylinder will run for between 1 hour 20 and 1 hour 40 minutes with the flame full throttle."
If all four of us are away we have yfive phones and at least one Ipad. The phones alone would cost a
a fortune to charge up and take hours.
Just glad we have a caravan and gave up this camping lark a long time ago.
