NEEWER NW-F4 Battery Charger: Fast four-channel charging for NP-F batteries

With wedding season approaching, the rush to keep cameras powered becomes very real. NEEWER NW-F4 Battery Charger handles four NP-F batteries at once and displays per-slot voltage, current, temperature and power on an OLED screen. Clear visual feedback removes guesswork for creators who must rotate batteries between takes.

⚡ At a Glance

• Charging Speed: Simultaneous four-channel recharging with selectable 8.4V outputs and per-slot OLED monitoring
• Essential for: Content creators and event videographers who rotate multiple NP-F batteries during long shoots
• Might frustrate: Run-and-gun documentary shooters; the 100W PD input requires roughly 4.5 hours to top up four fully drained 10,500mAh NP-F970s, so spares will not be ready between short location runs

Four independent NP-F slots recharge with three selectable output levels and automatic current detection. A 100W GaN USB-C charger and USB-C cable are included for fast input and wider device compatibility.

The Rapid Turnaround: Why PD 100W Super Charging Matters

Four channels accept NP-F batteries and the included 100W USB-C PD input distributes current across slots, with selectable outputs of 8.4V at 0.9A, 1.8A or 2.5A per channel and an automatic current-detection switch to match each battery. Direct impact: four 10,500mAh NP-F970s reach full charge in about 4.5 hours and four 7,800mAh variants in around 3 hours when using the supplied PD charger.

Multiple ready batteries reduce downtime during event days, keeping camera heads rolling between sets. Plan for the multi-hour refill window when you work back-to-back short shoots, as the fastest full recharge still takes several hours.

OLED Display and the Visibility Factor

An OLED screen shows real-time voltage, current, temperature and power for each slot and can toggle to show the charger's input voltage, current, power and temperature. User scenario: on a crowded kit table, a quick glance confirms which batteries are safe to use and which need longer top-ups.

Visible per-slot metrics eliminate guesswork and speed kit checks during busy shoots. Bear in mind that heavy multi-battery cycles will activate cooling measures, so expect brief rises in background noise during the fastest charge phases.

GaN 100W Charger – Built for Studio Versatility

A 100W GaN USB-C charger and USB-C to USB-C cable are included, delivering higher efficiency and lower heat than conventional silicone chargers; the wall charger also supports smartphones, laptops, earphones and several V-mount packs with manufacturer-stated full-charge times (for example PS050E in 1.4 hours).

Flexibility to top up laptops and V-mount batteries from a single PD brick reduces the number of chargers to carry. If you frequently need to power other kit alongside NP-F batteries, then the included 100W GaN charger and cable let you top up computers and packs without swapping power bricks.

❓ Frequently Asked Questions

Q: Can the charger revive batteries that have entered sleep mode?

A: The undervoltage activation function reactivates NP-F cells that fell into sleep due to low voltage, restoring usable capacity; pro-tip: allow a full charging cycle so the internal cells stabilise before placing batteries back into service.

Q: Will the cooling fan run for every charge cycle?

A: The fan only activates when internal temperature exceeds 50°C, keeping noise limited to heavy or sustained high-current cycles; pro-tip: position the unit on a ventilated surface to help dissipate heat faster and reduce fan run time.

Q: Can the included 100W GaN charger top up laptops and V-mount batteries?

A: The supplied 100W GaN USB-C charger supports smartphones, laptops and specified NEEWER V-mount packs with manufacturer-stated full-charge times; pro-tip: use the included USB-C cable for full PD speeds and avoid low-rated cables that reduce input power.

🏆 Our Verdict

Suitable for content creators and event videographers who need multiple NP-F batteries ready across a day of shooting. The OLED panel keeps charge metrics readable at a glance and the GaN brick runs cooler than older silicone chargers, reducing table heat during marathon sessions. For regular shooters who rotate several batteries, the four channels and safety features deliver clear long-term value.
