Three of us are touring Europe next month (camping).

We'll all have handlebar mounted phone chargers but I imagine we're going to need recharge facilities for various devices during the evening.

Can anyone recommend me a decent/reputable brand power bank / power station that can take a 12v input (SAE) to recharge while riding that we can all use to charge our devices once we get to the site? Probably need around 6 USB outputs I should imagine.

I've had a quick look and most coming up are either way too big, some cheap generic Chinese crap, or too small (single person use).

Anker is a decent make.

One to charge 6 devices is going to be huge though (think of the size of the batteries of the 6 devices all in one place, it has to be at least that big to charge them all once). Probably be better if each person took a smaller one and charged it themself.

Good point!

Being a bit of a mother hen though as the other two are only kids (20s) so wanted to have a backup for them as well if needed.

I was thinking of taking one of these as it will serve as a jump starter as well if needed (and also a lot of jump starter / power bank units only take a USB-C input whereas this one takes a 12v input):

https://www.amazon.co.uk/NOCO-GB150-UltraSafe-Lithium-Gasoline/dp/B015TKSSB8/?th=1

Just not keen on relying on USB socket on the bike to charge the unit we'll all be relying on to charge our stuff (had a USB output on the bike fail on my last bike), would rather have 12v straight from the battery.

BUT it's only got one USB output!

Might have to have a rethink...

Can't you rent a power station/bank unit instead?

Excellent idea taking one which will double as a jump starter - it's what I do myself, having been caught out a couple of times with a dead bike battery. But you certainly don't need a mammoth thing like that massive £282 Noco gadget - that will apparently give you 80 jump starts per charge and will start engines up to 9 litres! Noco (who are well though of) do smaller versions, though I have a Halfords one, which I use as a phone charger on occasions... needless to say I've never needed to use it to start a bike since I've owned it, but it's good for peace of mind. Mine is no longer sold, but this looks like the nearest equivalent:

Regarding the single USB output, which will be common to all of these boosters - you can certainly buy USB adapters (eg https://www.amazon.co.uk/dp/B0BGJCXY22) but I've no idea whether they would play nicely when used specifically to charge multiple devices at the same time.

If you're looking at spending that much, if you can find room for it, you could fit a leisure battery to your bike for much less.

Basically what they do on camper vans, you have a charge relay which only sends charge out once the main battery is fully charged, it then sends power to a second deep cycle leisure battery (a deep cycle battery is happy to be discharged a long way then charged back up repeatedly). Then you hook up your devices to the leisure battery, be that a multi-port USB charger or even an inverter.

The advantage of this is you never eat into the charge on the main vehicle battery.

They usually use a great big lead acid battery for this mounted on the van frame. people even run mivrowaves and TVs off them. You do get smaller ones too, so likes of a 3.5Ah deep cycle lithium battery is fairly compact and light and that's 3500mAh which is more than the biggest anker powerbank, it would run a fairly meaty sound system all night, a couple of lights and charge a lot of phones.

Problem with the smaller ones by Noco is they don't take a 12v charge input, only USB. Like I said I could use one of the USB outlets on my bike to charge it (I think there's one under the seat, not checked yet) but I think a 12v would be much more reliable as I can just plug it straight into the SAE from the battery. I could also sling it in the car for future use after I get back from tour as a backup.

The USB hub/splitter is a good idea, thanks. If it doesn't play ball, the other two will just have to wait their turn until I've finished charging my siht!

It's a nice idea, but probably more appropriate for a GS or something similar. Where would I put one on a M1000XR? At least with a portable power bank like this I can sling it in the car or indoors when I'm done with it, I probably won't want to carry the extra weight of a leisure battery the rest of the time apart from one or two long tours to Europe every year.

I use these buck converters to fit USB power supplies to vehicles that don't have them. I generally use a fused switched live but you could also directly hook it to the battery or whatever 12v charge socket you have.
