We bought Rail 5's and specced them up. Came with 2A (Compact) chargers but bought 4A (Standard) chargers when they came 'on offer'. Charging times:The base model (Rail+ 5) is actually surprisingly well specced, I'd almost go for that one ahead of the 8 or 9.7 and just swap out a couple of things. But it comes with a 2A charger, for an 800Wh battery, not a deal breaker but that thing must take half a day to charge up!
