The sondelux only delivers about 20% less power than the 28, so I'm pretty sure there is room there to back off a little on the power supplied.
Sorry I hadn't realised I was preaching to the choir.
Baring my E-werk requiring a replacement usb connection cable and now two B&M cache batteries (thank you SJScycles UK), my latest charging system, built circa 2012, has been problem free.
So enamoured with it, I invested in a mirrored (same) system for my Extrawheel trailer, so can you tell I'm a big fan.
