Small jump battery
 

...about paper back size and pretty cheap. Enough to power up your fuel pump and turn over the engine.

JUNOJUMPR - Most Portable Jump Starter (Presale - Ships May - June) | Juno Power

Microstart
 

Or use one of those- video -
From fully charged ( 4 blues) it started my F650 13 times ( the F650's own battery had been removed prior to test)
- then I checked the charge and I had 3.5 blues left!

Then it started my 2.5 turbo diesel 8 times before I got bored!

It recharges my phone, torch with 18650 batteries, ipod, steripen, satnavs, etc etc etc via its usb outputs.
Good kit
no connection blahblah blah - apologies for poor video-
Damn, I'm giving away more secrets!:smiliex:

Good kit? I'm sure it is, but we'd never know from the video:rofl:
(don't give up your day job just yet!) Hard to tell anything from that but your info indicates its very good!

The JunoJumper Fastship posted looks to be the real deal too ... aside from the questions some have regards problems with Li-Ion batts in various situations. Sometimes ... they just plain don't work. doh

I wonder how the Juno would hold up on the road? bashing round in luggage? and how long it will hold a charge? Must admit ... A GREAT thing to have if you're on your own. But if it just dies in a year and you're in Mongolia somewhere ... then what? (back to basics I guess):taz:

If you've got a partner or two or access to a car or truck, then all you need is small jumper cable to get most bikes going!

I even jump started my friends R1200GS from my DR650 ... which only puts out 200 watts total. Hook up the short jumpers and BINGO ... the GS started right up (DR650 running and revving at about 3500 RPM of course)

But the Juno says it will also charge Phones, Sat Navs or whatever ... question is ... how much to you have to spend on adaptors to charge each device? :innocent: I think custom adaptor cables is where the real money is!

:D

On my old Triumphs if you had a flat battery all you had to do was turn the ignition key the other way to EMG instead of IGN and it would start and run normally. Wish I still had that feature. I miss the robustness of the older bikes.

Please, don't tell us that a 6Ah battery can start a 2.5 diesel and then 8 times, REALLY!
And 300 A on those small wires would melt them. :nono:

Even if it could deliver 300A its not enough for a big diesel and a normal procedure would be to let a small battery be connected for some minutes, so it could charge the big original battery and then let IT start the car, so just the fact that they write that it can start a car directly, shows that this is bogus.

Those videos are also bogus, In one he "turns the power on" !!?? Where would you hide a 300A switch, inside that little box??
On the other video, he connects the Juno directly to a "flat" battery. Anyone who ever tried that will know, that the dead battery will draw a couple of 100Amps straight away and there will be arcing while connecting.
