Looking forward to seeing your install on F850GS Adventure, and would like to learn that power hub2 if have any issue with BMW power management system, some riders concern on that and would like to use Hex eZCAN to connect the can bus on motorcycle, eZCAN retail price is USD185.

Re the F850GS Adventure – the plan is to do an initial overview then a longer term follow-up in spring/summer, once I’ve accumulated more time and distance on it. But any of the accessories installed that are written up for individual reviews will of course feature the motorcycle as well.
PowerHub2 – there should be no issues with BMW on-board systems. As long as the main connections are made to the battery or an equivalent source and the switched trigger lead is connected to something like a switched accessory lead, license plate light or accessory DIN outlet, then there is no impact, or should not be – but I read of issues almost every day, usually due to users not understanding things. One of the best things of the PowerHub products is that they are small and easy to install, providing users with five switched outputs for those things that don’t need to be or can’t be managed best by a CAN-based accessory manager, like the HEX ezCAN or Denali CANsmart or Clearwater CANopener, or…
The CAN-based managers are excellent products in their own right – I use and install all of them and help evaluate beta firmware, etc. But optimal use of these products are for accessories that can be or need to be ‘managed’, such as switched lights or those that users want as adjustable that can then be done using a handlebar control and the multi-Function-controller or Jog Wheel; this is where the CAN-based systems come into their own. And yes, their output circuits can now be set to function as straight power outlets, but in many instances, this isn’t the optimal use of the system (although having PWM adjustable output for a heated gear circuit is one very good application for these systems other than for lighting).
But if something like a CAN-based accessory manager isn’t needed, but switched power is, then the Power Hub devices are far more applicable and effective. Many of us have a CAN-based controller for our front and rear facing lighting (providing tail/brake/deceleration-based output based on the onboard sensor and controller data) and we also have a separate power distribution module of some sort (be they straight switched outputs or PWM capable outputs – like the Neutrino Black Box systems). And where basic switched outputs will meet requirements, the Power Hub products are hard to beat regarding simplicity, effectiveness and cost.
As way of example, the F850GS Adventure will use a Power Hub 2 to provide switched power for two 2.4A USB outlets, the Admore SB Light Bar (rear-facing auxiliary LED product), a set of bi-colour handguard LEDs and, if so needed down the road, power for the rear-facing auxiliary LEDs kits typically installed on a top-box and/or side panniers.
