I briefly posted a few days ago about the RichardSolo 1800 battery pack. Here's a quick update from the RSNA battlefront on this device.
After lunch today, a friend noted that her iPhone was down in the red. Mine was down to about 40%, so out came the 1800 -- an hour later, her phone was back up to 100%. Another hour later, mine was back up to 85%.
Collectively it seems that we got just under 1.5 full charges out of the device -- an encouraging first test.
