Anker 747 Power Bank (25600mAh 87W)

Two of these in the kit, they're the crew-charging stations. Slightly more capacity than the 737 (97Wh vs 86Wh) but lower max output (87W vs 140W), which is fine because they're not primary camera batteries, one lives in Diego's van keeping crew phones, tablets, and walkies alive in transit, and the other lives at video village powering the Rode Wireless PRO charger, the Focus Pro hand unit, and emergency device top-ups. Four ports (2x USB-C + 2x USB-A) versus the 737's three, so it handles more devices at once, important when an entire crew is plugged in between setups. The 87W USB-C output will still power a Canon R5C if you need it as a camera backup, but it sits very close to the 100Wh FAA limit, so it always travels carry-on.
