Charge Two Sony NP-FZ100 Batteries Fast with USB-C Power
When you own a Sony Alpha mirrorless camera like the A7IV, A6700, or FX3, the NP-FZ100 battery is your lifeline. The SMALLRIG dual-slot charger promises to refill two batteries in about two hours via a single USB-C port, making it a compact travel companion for shooters who need reliable power on the go.
Key Considerations Before Buying
- Charging speed matters for busy shoots: This charger delivers up to 22.5W via USB-C, which can top off a depleted NP-FZ100 in roughly two hours per slot—faster than many standard wall chargers. If you often shoot back-to-back events, quick turnaround times reduce downtime.
- Dual-slot design versus single-slot alternatives: Having two charging bays lets you power a spare battery while using one in your camera. For Sony shooters who carry multiple NP-FZ100s, this eliminates the need for a second charger or waiting for one battery to finish before charging the next.
- Portability and power source flexibility: The charger relies on USB-C, so you can use a power bank, laptop, or car adapter instead of being tethered to a wall outlet. This is especially useful for location shoots, travel, or vlogging where AC power isn't always available.
What Our Analysts Recommend
In a camera battery charger, prioritize consistent voltage output and overcharge protection to avoid damaging your expensive NP-FZ100 cells. Look for a design that clearly indicates charging status per slot (e.g., LED lights) and supports pass-through charging if you need to power other devices. A compact, lightweight build also helps when packing for trips.
Camera Market Context
Market Overview
The camera battery charger market has shifted from bulky AC adapters to USB-C-powered solutions that integrate with modern power banks and laptops. Many Sony mirrorless users now expect fast charging, dual-slot convenience, and compatibility with the NP-FZ100 platform used across the Alpha and Cinema Line.
Common Issues
A frequent complaint is chargers that charge slowly or only work with specific USB-C cables or power adapters, leading to inconsistent performance. Some third-party chargers also lack proper heat management, which can shorten battery lifespan or cause charging interruptions.
Quality Indicators
Quality chargers include safety certifications (e.g., CE, FCC), intelligent charging circuits that prevent overvoltage, and clear LED indicators for each slot. User reviews that mention consistent charge times and no overheating are strong signs of reliability.
Review Authenticity Insights
Grade B Interpretation
With a Grade B and an estimated 10% fake review rate, the SMALLRIG charger's review pool is mostly trustworthy but has a small percentage of potentially fabricated or incentivized feedback. The 4.89 average rating likely reflects genuine satisfaction, though slight skepticism is warranted for the highest-scoring entries.
Trust Recommendation
Focus on reviews that describe real-world charging scenarios—like how long it takes to charge two batteries from empty or how it performs with different USB-C power sources. Verified purchase tags and specific camera model mentions (e.g., 'works great with my A7IV') add credibility.
Tips for Reading Reviews
For battery chargers, pay attention to comments about charging speed consistency across both slots and any issues with charging cables not seating firmly. Look for reviews that mention using the charger with a power bank or laptop to confirm USB-C compatibility.
Expert Perspective
The SMALLRIG NP-FZ100 dual-slot charger addresses a clear need for Sony shooters who want fast, portable charging without proprietary AC adapters. Its 22.5W USB-C input and two-hour charge time per slot align with current industry expectations, and the high rating suggests strong user satisfaction. However, the 10% estimated fake review rate means you should cross-check a few detailed reviews before buying.
Purchase Considerations
If you already own multiple NP-FZ100 batteries and value USB-C flexibility for travel or field work, this charger is a solid investment. Weigh the cost against SMALLRIG's build quality and warranty—since third-party chargers can vary in longevity.
Comparing Alternatives
Shoppers should compare this with Sony's official BC-QZ1 charger or other dual-slot USB-C options from brands like Nitecore or Wasabi Power to see which best fits your charging speed and portability needs.
