Yes, you're missing the fact that the heater is not 45 watts. This is misinformation. The heater is pulsed hundreds of times per minute to generate the heat. The heater can consume UP to 45 watts of power, but it does not constantly consume 45 watts. Average power consumption of the heater is based on the temperature setting and draw speeds of the user.These batteries still worry me. This is a 45W device. Assuming they are using 3.7v it takes ~12A. I have never seen a battery this size handle more than 10A continuous, in fact 10A may be a stretch for a battery this size I would of guessed, just at the sixe, that it would be more to 7-8A. Even if they are pulling 5v from the battery it will still be 8A which may fit under the specs of the battery but its close. And the fact you got two of them dead is not reassuring. I buy tons of these batteries for vaping and never had any DOA. This is a lot of Amps to be pulling on dangerous chemical batteries and I hope to hell they are not some cheap Chinese manufacturing.
Obviously I must be missing something because I don't think they would get it CES checked if it did not comply with safety standards but it still doesn't feel right to me. I truly wished they gave the specs of the battery. Too bad I won't be getting one til November because I would love to do some testing on the battery.
