When I first bought my Leaf, Nissan was charging >$1000 for installing a L2 charger. That just seemed like way too much money for what's basically a fancy safety switch. So I made do with the Leaf's included L1 trickle charger for my home charging needs. As posted here, I recently installed two NEMA 14-50 outlets in my garage - one for my Leaf, and another for my future Model 3. So it was time for me to order an L2 charger for the Leaf. Prices have come down considerably. You can easily find one for under $300 nowadays. If you go searching for an inexpensive EVSE on ebay, you'll see that Duosida keeps popping up as *the* inexpensive EVSE. I checked various forums (Nissan, Volt, etc.) where people tried these out, and they seemed to genuinely be pleased with them - no problems reported. The main limitation here is that these inexpensive chargers max out at 16 amps. Compared to the UMC included with a Tesla (40 amps), you would be charging at less than half the rate. For overnight charging at home, this might be perfectly acceptable to you (I would guess about 14 miles gained for every hour of charging for a Model 3). Since my Leaf maxes out at 16 amps, it was perfect for my use. These chargers have a pretty distinctive box shape, so you'll know it's a Duosida even if the brand isn't advertised: The trick here is that all of these Duosida chargers are exactly the same. The only difference is what type of wall plug is mated to the end. The back of the box includes a list of specifications that should look something like: That is, even the version sold with a 110v plug most likely still says that it's rated for 220v or 250v. All I did was buy one of these less expensive Duosida chargers, cut off the plug, and replaced it with a NEMA 14-50 plug which you can find at Lowes or Home Depot for $15: Utilitech 50-Amp 125/250-Volt Black 4-Wire Grounding Plug Leviton 30/50 Amp 3-Pole Angle Plug, Black I was able to confirm the specs listed on the back of the charger before purchasing mine. I've used mine a couple times now, and it's been working perfectly.
