In case your battery goes flat
 

Keeping it simple and avoiding all that 'push-puff-'n stuff' :Beach:
Fit a positive terminal accessible point
Use a small power bank weighing in at....300 grms!
Connect terminals-turn ignition key- and fire up engine - easy peasy
Why struggle! making technology work for you- it fired up my F650 13 times and used only 25% of its stored charge.
Once you're on your way again, plug in 12 volt charger to re-charge power bank- Sorted-
( btw-it can also charge up phones, tablets, water filters, computers, rechargeable torch batteries etc. via its USB outlet and it even has a torch built in. Free virtual fruit basket to whomsoever knows this product!)

That sounds remarkably like .... a battery. :confused1:

However I'm guessing it wouldn't be that easy so how about one of these -

This Portable USB Charger Battery Pack Can Also Jump Start Your Car


Available on Amazon for the price of .... a battery.

It's an auxiliary battery yeah. Pretty expensive if I remember correctly..

As this is the bodge fix section should we mention plugging in a battery charger then pushing the button?


This is a ticking time bomb of potentially melted wiring but if you have the charger and access to the mains.....


I've seen the results of trying to start a bus from a welding set too, don't try that unless you want to get on the telly.

gets the fruit basket- :smiliex: It is similar if not congruent. 200CCA Constant - 400CCA Max

Various versions available price range £30-£100, I assume they use some form of capacitor to provide enough Power to turn an engine over. Useful gadget especially as it can be used to recharge all the usual gadgets.
