I had a Caddy ELR before my Bolt. I was and am using a Bosch Power Xpress, only difference is when I got the Bolt had the electrician replace the 30 amp breaker with a 40 amp. The original had the right size wires for the 40. My question is the ELR in 5 hours would do a full charge for 39 miles while my Bolt in 5 hours will charge for about 125 miles. I assume the Volt has the same charger as the ELR. Is the Bolt's charger a higher capacity then the Volt, just curious.
