So going away for a fews days and need some power
Seen the bivvy boxs on ebay and the look OK. Just wondering if anyone knows anywhere I can buy all the bits to make one? Don't seem hard to make, just unsure on where to source everything at a decent price
Also, is there anything stopping me using a car battery, wiring a USB socket to it (inline fuse) and using that? Gotta last longer than a tiny 9ah battery?

I just use a normal non-fishing power pack off amazon. 26ah for under £20. The bucket power packs, in my opinion are 99% carp tax.

Another option could be a 30 amp or so lead acid battery and a power inverter in a plastic tool box.

Would I need an invertor if I used a USB socket that's for the like of a car?
Don't they have the invertor within the device? That way I could use a spare car battery I have laying about?

It's not an inventor you want unless you intend to feed your phone with AC which I assure you it would not like.
DC to DC step down convertor 12v to 5v for about £8 to £15 if your phone will not accept 12v. A fast charge function would accept a higher voltage and current, never had much to do with it though so best to check.

So something like this wired direct to a car battery wouldn't work?

You can get versions that do the same with tails but like I said you need to check if your phone or whatever will accept 12.6 volts
Buck step down convertor will drop the voltage if required.

Thanks mate... Just checked and as its a note 20 it can take 15v as its one of them fancy fast charing devices

For years I have just used a normal car battery, usually my old ones off my car or from a scrap yard. So long as you do not drain all the power out of them they will last a long time. But drop the battery level to much and you can kill the battery life all together and it will not charge. Off top of my head you need to leave about 20% of the charge.
You also need one of these and from that you can plug into it multi cigarette sockets with USB ports combined.

A leisure battery is best though.

Thanks for that zac, that's exactly what I'm thinking, I have a old car battery-and a.leasure battery is only £40 for 50ah. I'll just replace then cigarette lighter with the USB quick charger that I linked and should have power for weeks

have a look on utube loads of tutorials on how to build them

Phil, as zack says you need to keep some charge in whatever battery you use.
Different types have different safe d.o.d. ( depth of discharge)
Normal wet acid is 50% so try and keep the voltage over 12.2 volts as a minimum for a good battery.
AGM (absorbent glass mat) can be discharged much lower and is spill proof but more expensive so might not worth it for what you need.
You will also have an advantage over the off the shelf power packs in that they normally rate their ah capacity using 5v. Your ah rating will be at 12 v so will store 2.4 times more energy, which will more than offset not fully discharging your battery.

If its just for phone + ecigs for a few days than you'd be fine with one of the small-ish ones off Amazon
Anker Powercore is the one I have its something around 22,000 MaH and it will charge my phone 5 or 6 times, as well as charge my Bivvy light as and when needed.
Should be more than enough , A car battery would be serious overkill IMO.

I use a Lipo battery
Put it into a clear box with lid and run a - /+ to two brass 6mm bolts protruding through the wall and I can then use as my charging ports 👍
