[QUOTE="Jeff Cash, post: 22077, member: 4689"] My thoughts after receiving the S90. My S90 arrived earlier this afternoon via Amazon Prime. It was half charged, connected the power supply and around 6 hours later, it was fully charged. Took my Spark out this morning to catch a bit of the rare snowfall that we have had here overnight in Houston. I intentionally wore down my three batteries to 20%, 30% and 45% respectively. Plugged the batteries into the Smatree powerbank and less than 20 minutes later the first battery (45%) was fully charged. I got a bit distracted for a little over 30 minutes, checked the charger and all remaining batteries were fully charged. I'm fairly impressed as this would allow me to stagger and cycle out batteries and stay in the air for over an hour easily with very little downtime. I didn't bother to check voltage since it never got any hotter than room temperature. I still might do that at some point but I was a little too busy last and this morning. I won't necessarily recommend the S90 yet due to safety concerns, but I can attest to Smatree's claims regarding speed of charging.
