PB-S290S provides at least 200W/16A high load even at 1% power to drive high-power cameras and on-camera devices together. High-load cells also ensure battery life compared to normal-load batteries under full-load output for a long time. The PB-S290S has 4 D-tap output sockets with 10A/120W load and 1 USB 5V/2A socket, to power other on-camera devices. The PB-S290S supports 6A fast charging via the SWIT PC-P461S or S-3812S fast charger to save more than 50% of charging time. The 290Wh PB-S290S battery can be charged from 0 to 80% after 2.5 hours and fully in 3.8 hours. The built-in OLED can display the percentage of remaining energy, remaining working time, and battery cycle times, and supports the display of viewfinder information on SONY and RED cameras. When an overcharge, overcharge, short circuit, high/low temperature is detected, the battery protects itself and displays protection information. Steps can be taken to reactivate the battery to ensure its best condition and prolong its life.
