Review on Roadpro 12V Fused Replacement Cigarette Lighter Plug with Leads - Black (RPPS-225) by George Johnson

The plastic case and the mechanical parts seem to be of good quality. However, this unit comes with a smaller 2A fuse, which is ridiculously small for the connected red/black wires coming out of the case. No problem, just add a bigger fuse, right? Unfortunately this box uses a custom 6x30mm fuse not found in auto parts and hardware stores as it is slightly smaller in diameter and length than the very common Bussman or Littelfuse type 3AG. 6x30mm fuses can be found online, but be aware that some suppliers incorrectly substitute AGC (3AG) 0.25"x1.25" fuses for 6x30mm fuses. In some applications the tolerances can be large enough that these two types can be interchanged, but not this block.
