Thanks. I double-checked and I do have a 50-amp breaker on my range circuit.

It takes my Dell battery about 3/4 hour (2700 seconds) to go from fully discharged to fully charged using the stock AC power supply. That implies that at 100 percent charging efficiency the battery is charging at close to 1 amp. This is a far cry from a 9 second recharge at a 920 amp charging rate.

Yup, lots of hype in the article.
