Oh as in he doesn't trust switch live??I think he meant the opposite: he doesn't want to tap into the battery and wants to be sure the feed is off when the bike's ignition is off. That is agreeable

I guess the easiest solution will be to pony up the cost of the TB1.
No, I want a switched live circuit to avoid unwanted dead battery.
If you have money to burn then you can always go down the ezcan route!! As that allows you to set the amp to the socket
I use the spare connection I have on mine to charge up my laptop/portable power brick when on the move

This is correct. The Denali switched power adaptor can be used to switch the power to one of these https://www.infinitymotorcycles.com/product/oxford-junction-box
Which could have one to four of these, or similar, connected to it https://ultimateaddons.com/products...ast-charger-usb-and-type-c-with-led-voltmeter
Thanks again, I haven't had any exposure to ezCan and watching their video on the tube, it looks like a lot of faff to fit and program. I only want low amp charging capability so will probably go with a home spun number to achieve this. I tried to run a one to two charging cable from the forward USB port but, it only powered one output at a time which made me curse. I will dust the multi-meter off and see what output the two terminals on the GSA are producing. I could run a cable forward from the rear left socket with a USB port on the end, that'll allow me to charge two things at once which is better than the current output.
BTW, I just noticed your location, I'm currently in the process of moving down Gosport way.
It's only worth it if adding lights etc
I think the TB will be your best option and it's very simple to fit.
It's nice down south...we actually get decent weather but always welcome to get in touch if you need any advice (if you're new to the area)....
I think this with one of their splitters will cover my requirements.
Cheers, not new to the area, lived in the area about 15 years ago, looking forward to being by the sea again. Forgot to update my location, I'm currently in West London which isn't great but the weather is better than the West Midlands.
Little heads up.Also one of the lads found this device which is basically the same as a Thunderbox but cheaper
Though by the looks of it each output is limited to 5 amp which may not help with 4 USB devices charging but worth a look
By and large I like Oxford bike products, they are generally fit for purpose and cost less than ‘big brand’ name kit. I have a Fuseblock fitted to one of my bikes and was looking for a similar solution for the other bike when I came across this :
Oxford Junction Box -12V with fused power outlets : Oxford Products
Oxford Products Ltd (OXFORD) - a global leader in motorcycle and bicycle products. Established in 1973, OXFORD is now one of the world's leading suppliers of products to the two-wheeled industry.www.oxfordproducts.com
Has anyone here used one and care to comment on them please ?
I’ve got one of the Oxford boxes and it’s not quite the same as a Thunderbox. The Oxford one ( which can be bought even cheaper on Amazon for a non branded item) relies on a switched live connection to turn it on.
The Thunderbox as I understand it connects to battery only and senses the bike running and switches on.
The without a switched live the Oxford item will be powered all the time.
The TBU01/02 can be connected either way. For it to work best they also require a switch live (I have the 01)
But you're right I believe the TBUSB is only connected one way without switch live.
I don't think the TB are restricted to 5 amp per channel/connector where the Oxford is.
I too have a ThunderBox (on my Guzzi, not my GS, I have a EXCan on my GS), but not for USB (I already have multiple USB on my bikes).
I've tried it in the "standard mode" when it powers up as the alternator output voltage gets up (probably around 14v) - which is pretty handy as it doesn't take power from the battery until the bike is running (leaving most battery power for cranking the motor)
Also tried the switched live, but I have gone back to the first mode to get max cranking power
This is a great vid:
The PDM-60 is probably a slightly better option, but double the price (around £220). The PDM is more programmable, offering more options... If I see a PDM-60 at a good price I will swap out the ThunderBox on my Guzzi.
I'm using Thunderbox for heated grips, GPS, and potentially, heated clothing. I tried wiring the DialDim via the Thunderbox but it didn't shut down properly!

I use the thunder box. Run aux lights, multi plug usb, sat nav and a spare for the compressor which I have never needed. No issues, small enough on a 1200r to hide it away, simplest of simplest installations I have ever had to do. Well chuffed with mine. Oxford seems larger, less waterproof. All my gear powers up before I have even lifted the side stand. I connected it without a switched live, relying on its own power up/down magic. Never had a flat battery in 2 years due to not switching off. Well worth the money I paid for it
Morning, does anyone know if the power outlets on a 1250GSA (forward USB and rear DIN socket) are switched live or constantly live?
