WiFi Pineapple NANO
The WiFi Pineapple NANO requires 9W for stable operation under high load. This figure accounts for a 2.5W USB accessory in addition to maximum utilization of the CPU, SD card and radios. Power is provided from the male USB type A plug. A USB Y cable is provided with the WiFi Pineapple NANO.
WiFi Pineapple TETRA
The WiFi Pineapple TETRA requires 18W for normal stable operation. While the device may function under minimal load with less power, system instability may occur during peak load.
Power may be provided to the device by any combination of USB UART, USB ETH, or 12V DC ports. The 12V DC port accepts a standard IEC 60130-10:1971 type A connector with 5.5 mm OD, 2.1 mm ID (center positive).
The UART and ETH ports on the WiFi Pineapple TETRA will accept power from combined USB sources, such as from computers, wall adapters or batteries via USB Y cables. There is no risk of providing too much power from standard 5 volt USB sources as the WiFi Pineapple TETRA will only draw as much amperage as needed.
Most modern computers are capable of providing the necessary amperage from their USB ports to power the WiFi Pineapple TETRA using two USB Y cables. Older computers and many netbooks however may not provide enough continuous current for stable operation.
When calculating total power in wattage, multiply the voltage and amperage. USB sources are always 5V and may vary in amperage depending on configuration. Many older USB 2.0 ports are limited to the 500mA specification while newer USB 3.0 ports can deliver 900mA and above. Typically notebook computers with USB charge ports (indicated in yellow, red or by lightning icon) will provide even higher amperage.
