There website is awful. Do you know which one to get for a normal 110 plug to be converted to the 220? As far as the wired option above, looks like a pretty serious fire hazard!

This is wrong on so many levels. First, combining 2 out-of-phase NEMA 5-15’s will provide 15 amps at 240 volts, You double the voltage but you don’t increase the amperage. Second, the example you show is dangerous because as soon as you insert one plug, the other will become hot and therefore an electrocution hazard. Don’t do this.
The Quick220 is a good solution because it has a switch to prevent the electrocution hazard I just mentioned but it, too, must be used carefully. Do a search on this site for Quick220 and you’ll find discussions on the dangers of misusing the Quick220.
That thing is a shock and fire hazard. Don't even think of using it.
The Quick220 is a somewhat better approach as it is properly wired and has relays for safety. But it won't work with GFCI receptacles. And it has other safety problems too.
Best is to hire an electrician to install a dedicated 240V circuit.

Seriously - please don't skimp on costs and/or the lack of level 2 charging capabilities with these kinds of "hacks". They're not within miles of electric code and can easily shock/kill you or someone else. Even worse, they could easily start a fire if something goes wrong in even the smallest of ways.
As already stated - hire an electrician! The amount of money spent for this particular purpose is pennies compared the costs of repairing damages when one of these ideas goes wrong.

6-20 would be 240V and charge twice as fast as 5-20 at 120V (3.84 kW vs 1.92 kW). 6-20 would charge 2.67 times faster than a standard 5-15 120V (1.44 kW) outlet.
Then you should take a look at the Quick 220 as mentioned earlier. Is a much safer option, even if it isn't perfect for everyone.

Look for dryer outlets, these are normally 240v 30a and might work for you. Other option is to talk to the landlord about the installation they may allow it or even share the cost.
Good suggestion. If there is a dryer outlet available, something such as the Dryer Buddy or the NeoCharge would allow the outlet to be shared.
As stated above - 2 15a 120v outlets would combine to a 15a 240v outlet.
But, for everyones safety, if you must do it, use a quick220 device or get with the landlord about authorizing you to hire an electrician and modifying the property. if it is near the breaker box it might now cost much money.
If anyone (landlord, their designee, family, friend) pulled out one of the plugs in the self made rig and was electrocuted it would be much bigger problems financially and mentally.
