Powering laptops in the field

[MattJenko]

Morning All,

Just a question regarding imaging out at dark sites. I currently image from my garden, or at places where there is mains power. How do people power their laptops out in the field, as my laptop battery certainly will not last more than a few hours away from a plug socket?

Thanks

Matt

I use the Halford's Phaze Jumpstart unit - it has 2 x 12V vehicular sockets (one powers the 'scope).  It also has a USB socket which could power my tablet (controlling the GoTo) if necessary.  That could power your laptop.

There is also a bright white lamp for when you pack away.

17Ah.  A great unit - no problems yet!

Duracell do 12 volt to whatever voltage convertors(DC/DC) for many different laptops. I have had one for some time. Seem good quality. I also use a LiFePo4 Tracer battery, but not cheap. You could do as I did before use a 55Ah 12 volt gel Golf Buggy battery. Heavy but safer than ordinary lead acid, as spill proof.

I've got a few of these, you need to get the right one for your laptop.

Hi Matt

There is a thread on this at

Small 2000 watt generator.  At least 8 hours on a fill. Powers the laptop, camera and mount. Might have to try a small coffee pot sometime.

Does anyone lug about a car battery?  In the past when I had a fish tank I would use my 68's battery and an inverter to run the heater and filter.  If I recall it would work for 8 to 12 hours.
