Portable charger use every day is fine . Probably better for your battery due to lower heating of battery and charger in the car.
For home unit get a Siemens Versicharge . I just installed one . These are cheap on ebay. The quality is good and has adjustable current 32A , 24A, 16A, 8A on 240V
You can get these for around $320 and are safe to use.
Dont trust the China stuff to be complaint to safety standards.
Most do not pass the diod test or short test.
The charger is a GFCI and makes sure there is no power applied when car is not ready for power . And should cut the power in case of internal short.
The charger also makes sure the contractor inside is not faulted ( welded contacts) . Which would be dangerous to you in case of working in rain.
Better play it safe.
Go with a proven solution
Also the Pacifica factory charger can do 240V at 12A with a simple adapter = 6h charge time. That is your cheapest option and is safe. The pacifica charger is good quality and can do 120V or 240V charging no problem . Same as the newer Volt chargers.
The adapter to go from 240V plug to 120V plug will set you back ~$30..$40
