SmallRig 4-Slot Charger for Sony NP-F970 - Fast PD 100W Charging

In this review the SmallRig 4-Slot Charger for Sony NP-F970 is evaluated as a compact, travel-ready solution for photographers and videographers who rely on NP-F style batteries. The bottom line: it is best for users who need to recharge multiple NP-F batteries quickly and track each cell as it charges, since the built-in OLED status display and PD fast-charge capability make multi-battery charging straightforward and efficient.

Key Features

• 4-Channel Charging: Charges up to four NP-F batteries simultaneously so you can replenish multiple spares between shoots without juggling single bays.
• PD 100W Fast Charge: Supports high-efficiency 100W PD input which, with a suitable PD power brick, can fully charge four large batteries in a matter of hours.
• OLED Status Display: The integrated OLED clearly shows the charging status of each slot and the USB-C input power so you always know when batteries are ready.
• Wide NP-F Compatibility: Works with common NP-F series cells including NP-F970, NP-F750 and smaller NP-F types used across camera rigs and lights.
• Safety Protections: Each port includes overcurrent and short-circuit protection to protect batteries and connected equipment during charging.
• Portable Design: Compact and lightweight construction makes the charger easy to pack for travel and location work without adding bulk.

Who It's For

This charger is ideal for independent filmmakers, event shooters, and run-and-gun creators who keep several NP-F batteries in rotation and need predictable, simultaneous charging. The OLED gives clear, slot-level information which is helpful when managing a kit of mixed-capacity batteries.

It is less well suited to users who never charge more than one battery at a time or who do not own a high-power PD brick; to achieve the fastest multi-battery charge rates you should pair it with an at least 80W, preferably 100W PD charger.

Pros & Cons

Pros

• Can charge four NP-F batteries at once, saving time between shoots.
• 100W PD input enables high-efficiency fast charging when used with a compatible power brick.
• OLED display provides clear, real-time status for each slot and input power level.
• Built-in protections add safety for both batteries and charger.

Cons

• To reach full-speed charging for four batteries you must use a high-wattage PD charger; lower-power bricks will slow total charge time.

Specifications

Our Verdict

The SmallRig 4-Slot Charger for Sony NP-F970 is a practical choice for creators who need to keep multiple NP-F batteries topped up with clear status feedback and reliable protections. When paired with a proper 80W to 100W PD power brick it delivers fast, efficient charging and good value for users who regularly rotate several batteries during shoots.

Frequently Asked Questions

Can it charge four batteries at full speed?
Yes, but to achieve full-speed charging for four batteries you should use a PD charger that supports at least 100W; lower wattage will reduce charge rates.

Which NP-F batteries are supported?
The unit is compatible with common NP-F series batteries including NP-F970, NP-F750, NP-F570 and NP-F550.

Is the charger safe to leave connected overnight?
It includes overcurrent and short-circuit protections, but as with any charging device it is sensible to follow safe charging practices and avoid leaving equipment unattended for extended periods.
