Voltmeter Rec Please

Can anybody recommend a digital voltmeter for the VFR to fit a 30mm hole?

UK based please.

I use one of these on my track bike. Dual USB ports are handy for powering my front & rear cameras so I don't have to deal with charging batteries.

I suspect there are, but which of them are quality?

Thanks Danno, that looks good.

Here's selection criteria I used:

- all alloy-construction for durability

- high-power USB output for overhead when used with low-power devices

- fused harness

Amazon has generous return-policy, so last resort, I can get refund. Had mine for 3-yrs now without any issues, even with numerous 45C trackdays.
