kLite alloy handle bar mounting system.

Given the max output of the dynamo hub is only 3w, when pulling a large amount of power from the USB charger, (at same time as running light) and when using a USB ALWAYS ON BAR SWITCH / WIRE LOOM, the light will go into POWER SHARE MODE, when MAX power limit is hit, the system gives USB preference to USB, and thus center LED will not light, to AVOID Power share mode, its best to do charging in the DAY w light OFF, to maxamise the USB power coming from the dynamo hub.

The body of the USB charger is waterproof, but the USB sockets are prone to rust if left in the rain, one option is to use dielectric atuomotive grease, if run outside in the rain or place in a top tube bag or frame bag for protection.

In General its OK to run the kLtie ULTRA light w heatsink facing up or down, just don't mount it sideways.

YES the kLite bar switch wire loom ONLY passes power from the hub to 2 plugs, you can wire any dynamo light to the short lead of the wire loom, just make sure you add a XT30 plug so its then plug and play.

Yes, you can, however it must be wired correclty so that the rear dynamo powered light, is ON at the same time. Most rear lights are already connected to the front light, so just add XT30 plug to your old system and your good to go.

Most USB device's can be charged, however due to the max power limit of the hub, you won't be charging as quick as modern wall chargers. we recommend a 10,000mAh power bank, take 2 if needed, this way you can use one, charge at same time, or even loose one...or have one die...great backup, even better to use QUICK CHARGE power banks to take power from the wall up to 3x faster than normal power banks. QC3.0 or USB PD are popular quick charge formats

No, the power from a dynamo hub is AC, the power from a battery is DC, thus you can't use a battery to run the kLite system, only a dynamo.

Riding thru the nite is a proven way to reduce weight and comsumables on a trip.

Yes, but due to the small amount of copper inside a bottle dynamo you wont' make enought power to fully light up the kLite light, as it would be from the more powerfull dynamo hub.

Yes, the main wire looms, SHORT Lead, goes to the light, this PLUG is the one that works from the switch, please just SWAP the leads around, so to make sure LONG lead goes to the USB charger, short lead to light, as on the race system, the long lead is ALWAYS ON.
