Watson MTC-4237 Overview

The Mini Twin Charger for NP-FZ100 Batteries from Watson is a compact and portable solution designed to simultaneously fast charge two Sony NP-FZ100 type batteries when paired with your own 27 W or higher USB-C PD power supply. A bright display offers easy viewing of each battery's independent charging status and shows a fast-charging indicator when a PD power supply is connected. Intelligent circuits with a dedicated safety cutoff protect your equipment by automatically guarding against overheating, overcharging, and power surges. The compact size makes it a space saver in a gear bag or on a desk, and the rubber feet provide a nonslip grip for tabletop surfaces.

NOTE: The Mini Twin Charger requires a separately available USB-C power supply. To achieve the fastest charging times, use a PD-compatible power supply rated at least 27W (30W is recommended).

Simultaneous Fast Charging
The Watson Mini Twin Charger accepts two Sony NP-FZ100 type batteries for independent and simultaneous charging. Connect a 27 W or higher USB-C PD power supply and fast charge both batteries in just two hours. This allows you to power up the batteries for your next shot or quickly charge backups while you're out in the field.
High-Visibility Display
The bright, independent battery charging status display shows each battery's progress, allowing you to quickly select the fully charged battery for work and leave the other charging. A fast-charging indicator illuminates when a PD-capable USB power supply is connected, letting you easily see if the power supply supports fast charging.
Intelligent Circuit Protection
Automatic circuit protections detect currents exceeding the battery limits and enable a safety cutoff. This ensures the batteries don't overheat and guards against overcharging, short circuits, and power surges.
Compact and Portable
The charger's compact size makes it easy to take with you wherever you travel. Having the batteries upright allows a small profile measuring 3.5" wide and 1" tall so the charger can easily find room in your kit bag.
Nonslip Feet
Nonslip rubber feet prevent the charger from slipping around on a desk or tabletop surface, keeping the workspace tidy and the batteries in the same spot as you left them.

A compact way to keep 2 batteries charged and ready. Works great

By Jim

This Watson Mini Twin Charger is a convenient and easy way to keep my NP FZ100 batteries ready to go, and I really like how small it is. Being able to charge two batteries at the same time is a big improvement over having to rotate them through a single charger. The display is also very useful because I can glance over and immediately see the charging status of each battery. It is a small thing, but being able to tell what is happening without having to guess is something I appreciate. The compact size is probably my favorite part of the design. It takes up almost no room in my camera bag, so there is really no reason not to bring it along. The built in safety circuitry is another feature I like having in a charger. The automatic protection against overcharging, overheating, short circuits and power surges adds some reassurance. This is a simple accessory, but it solves a very common problem in a small and convenient package. Having two batteries charging at once while taking up very little room makes it a very helpful addition to my kit [I have received this product in exchange for my honest review.]

Light weight and very affordable!

I have about 10 Sony NP-FZ100 batteries for my two fx3's and my a74 so this portable charger comes in handy especially when I travel. Here's what I love... 1. It's light weight 2. The led display is very bright 3. This is incredibly affordable and makes for a good addition to my kit when I travel. This charger can charge the battereis fast, but it requires a pd charger. I tend to prefer a slower charger because I believe it helps maintain the battery life longer through the years. [I have received this product in exchange for my honest review]
