Anyone seen these before?

Hi,

Was looking at power solutions for my secondary mirror dew heater and came across this.

http://www.amazon.co.uk/gp/product/B00O0M713S

12v, 16v r 19v, 5v USB and 16.8AH capacity? £50 I paid to give it a go - don't care about the car start function. Seems to have good reviews online and be solidly built. Has a fuel gauge too which lights up. Loads of cables in the box. Small and light -  I reckon I could hang it from my secondary cage with few problems and you wouldn't even know it was in a pocket. Going to be trying it eagerly the next few weeks and seeing if it is any good. If not, being from Amazon they can have it back

So anyone else seen or used this type of thing before?

I have a cheap 5V only version that powers my EQ3-2 mount for days on end another one is used with a step up buck converter to power my camera, 4800mA H but only a fiver each I would like a multi voltage one though.

Looks like a considerably less expensive version of the Tracer.

I think it is a Tracer but something like a 5Ah type......

Its not 5AH, it is 16.8AH...

Yeah I looked at getting a couple of them and hooking them together to run the dew heater but with the added benefits this had for actually being 12V and 19V I went with this. I think if I ran this flat, it would be a good 40 hours worth of use with a dew heater on the secondary. Now I only observe for 5 or 6 hours a night at most so I think a couple of days before needing charging to top it up should be easy for it to handle.

I would read that as 1.68AH the box has 16800mAH i might be a nought out see what others think......

See http://www.rapidtables.com/convert/charge/mah-to-ah.htm

16800 = 16.8 AH
