Yes. All 2011 and 2012 models, regardless of trim package, only came with a "3kW" onboard charger that can charge up to 3.8kW or up to 7 hours from a dead battery to 100%.
It wasn't until the 2013 model Leaf that the "6kW" onboard charger was an option, which can charge twice as fast, reaching 100% from a dead traction battery in 4 hours or less.
Of course all this depends on what the Leaf is plugged in to. If it's a regular household socket and it will charge at a little over 1kW and take up to 21 hours to charge using the same J1772 port.
Same with CHAdeMO. It can charge as fast as 50kW, if the CHAdeMO charger is built for it.
