FXLION Nano ONE V-Mount Battery 50Wh - Compact Power for Cameras

In this review the FXLION Nano ONE Upgrade V-mount battery is presented as a compact power solution for filmmakers and photographers who need reliable, portable energy on shoots. The bottom line: this tiny 50 Wh battery is best for users who want a true one-hand V-mount pack that still delivers up to 8 A output and multiple ports for powering a camera kit and mobile devices; its small size and direct charging feature are the single biggest reasons to buy.

Key Features

• Mini and Portable: At about 0.68 lbs and roughly 3.94 by 2.79 by 1.38 in, it fits in one hand and is easy to carry between locations.
• 50 Wh Capacity: The pack provides 50 Wh of energy with up to 8 A working current to meet higher draw devices like monitors and some camcorders.
• Multiple Outputs: Built-in D-Tap, USB-A and USB-C outputs allow simultaneous powering of DSLR cameras, monitors, wireless transmitters, phones and tablets.
• Direct Wireless-Style Charging: The upgraded design supports direct phone charging through a dedicated interface with up to 15 W output for convenient on-the-go top-ups.
• Fast Charging Options: Using a V-lock/D-Tap charger (16.8 V/2 A) or PD Type-C (15-60 W) cuts recharge time to roughly 2 to 4 hours, reducing downtime between shoots.
• Status Readouts: The built-in 4-level LED indicator and OLED screen show remaining percentage, voltage and output values so you can avoid unexpected shutdowns.

Who It's For

The Nano ONE Upgrade is ideal for run-and-gun shooters, gimbal operators and content creators who need a true V-mount form factor in the smallest possible package; it suits anyone who values low weight and multiple ports to power a camera plus a phone or monitor simultaneously.

It is less suitable for productions that need very long runtime or to power heavy-duty cinema cameras for extended periods, where larger capacity V-mount packs would be a better fit.

Pros & Cons

Pros

• Extremely compact V-mount form factor that is easy to carry and mount in tight setups.
• Versatile outputs including D-Tap, USB-A and USB-C enable powering several devices at once.
• Short recharge times when using a proper V-lock or PD Type-C charger reduce shoot interruptions.
• Clear status feedback from the 4-level LEDs and OLED screen makes remaining runtime and voltages visible.

Cons

• At 50 Wh capacity it provides limited runtime compared with larger V-mount batteries, so it may not suit long shoots without spares.
