I have a XTAR VC4 in home. Very happy so far.
Just set and forget. Anything.
But am after a small 2 cell unit for in car\Boat.
Which would be the best, IE reliable unit of the above.
The S2 or prev model. Or one of the others.
Which both look and spec the same. Just different names?.
OR. Just buy 2 X S1’s on sale.
