Running out of power mid-take is one of the few production problems that’s completely avoidable with the right adapter plate. SmallRig’s power accessories let you swap a camera’s small proprietary battery for a much larger external one — NP-F, V-mount, or a USB power bank — without needing a completely different camera cage or rig.
NP-F Battery Adapter Plates
These plates take a common, inexpensive Sony NP-F/L-series battery and convert its output into whatever your camera’s dummy battery connector or a DC barrel needs — turning a battery designed for old camcorders into a legitimate external power source for a modern mirrorless or cinema camera.
- NP-F Battery Adapter Plate, Lite (3018) — [AFFILIATE LINK: SmallRig NP-F Battery Adapter Plate Lite]. A simple dual-DC-output plate for powering accessories like monitors and wireless receivers directly from an NP-F battery.
- NP-F Battery Adapter Mount Plate, Advanced Edition (3168B) — [AFFILIATE LINK: SmallRig NP-F Battery Adapter Plate Advanced Edition]. Adds a 36W USB-C port (which can output power or charge the mounted battery) alongside 7.4V/12V DC barrel outputs — built specifically to power cameras like the BMPCC 4K/6K/6K Pro and Canon R5 C off a single NP-F battery.
- NP-F Battery Adapter Mount Plate Kit with dummy battery (4696 series) — [AFFILIATE LINK: SmallRig NP-F Battery Adapter Plate Kit with Dummy Battery]. Bundles the plate with the correct dummy battery for your specific camera (Canon LP-E6NH, Sony NP-FZ100, etc.), so the whole kit works out of the box instead of requiring a separately-purchased dummy battery.
Power Bank Adapters
Power Bank Adapter (3085) — [AFFILIATE LINK: SmallRig Power Bank Adapter]. A dummy-battery adapter with a flexible silicone strap that lets you power a camera directly from almost any USB power bank you already own, supporting common dummy battery types (NP-FZ100, NP-FW50, LP-E6, EN-EL15, NP-W235, DMW-BLF19). This is the cheapest way into external power if you don’t already have NP-F batteries — you’re reusing a power bank instead of buying a new battery system.
NP-F Plate or Power Bank Adapter: Which Should You Buy?
- Already own NP-F batteries (from lights, monitors, or a previous camera) → NP-F adapter plate — one battery type powers everything.
- Don’t own any NP-F gear yet and just want longer runtime cheaply → Power Bank Adapter with a USB power bank you likely already have.
- Shooting BMPCC or another camera with a genuinely short battery life → prioritize the Advanced Edition NP-F plate with USB-C pass-through so you can top up the NP-F battery itself between setups.
- Always confirm the correct dummy battery variant for your exact camera model before buying — this is the single most common return reason for adapter plates.
Bottom Line
If you’re already invested in NP-F batteries for lights or monitors, an NP-F adapter plate is the natural next purchase — one battery standard covers your whole kit. If you’re starting from zero, a Power Bank Adapter is the cheaper entry point since it reuses hardware you probably already own.
