remember, these can not fly on planes , in either carryon or in luggage. 20000 mah is max usually. my last 27000 was taken from me. Nice to have but it won't fly.
Wouldn't this be just under the 100watt-hour limit? 27*3.6=97.2watt-hour
it would be but the voltage output is 5 volts so the math is 5 * 20,000 mah = 100 watt hr. ( usb is 5 volts output ) Guarantee that 27000 will not get through security. I fly all the time, first time I took a 27k it was taken
Output voltage shouldn't be the metric used. By that method, the 120v plug would make it 3,240 Watt-hour.
Yup I had the same thing happen earlier this year, flying to Asia in general they triple check each battery, they told me 18,000 or less.
Yeah, from the TSA website: The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
Sadly TSA can use that line for just about anything or anyone. Hence why I avoid TSA approved products (fairly large TSA approved carry-ons etc...)
and stick to sure bets.
Not saying that won't take them over 27000 but I have flown a pair of 2700's across the Atlantic and then domestically 3 or 4 times. I had no idea I was breaking any rules maybe that is why I never lost them. They ALWAYS pull them out and scan them separately but they have given them back.
Me too, I had a 27000 and several 10000 ones and Asia freaks, they'll inspect it looking for the mah in China and Japan. I would be careful. I know Ravpower says 27000 is fine, but people there won't negotiate.
