Hi All,
An electrical engineer told me that the faster the charging time for any rechargable lithium-Ion battery will reduce the overall life-cycle of the unit. Slower charging causes the battery to absorb more of a charge. This fills up the charge in the battery more fully thus incrementally increasing battery longevity. While the 150mA adapter may be inconvenient for some, my 1300mAh Echo takes about 8 hours to charge, but I get way over double that time vaping. I love my Echo!
