Customers have reported that FloBLE readers are losing connection while operating for long stretches. We thought this could be because batteries were draining out so we studied the overall power performance of the FloBLE Plus (ACR1255U-J1) in detail. Ultimately, we wanted to know if a standard USB port (USB1.0 from PC) would enough to keep a FloBLE connected and scanning continuously. TL;DR: Yes! like the FloJack (ACR35), the FloBLE (ACR1255U-J1) is capable of continuously scanning NFC tags while powered by a standard USB port from a PC or wall adapter.
