FXLION Nano ONE V-Mount 3400mAh Battery - Compact Power for Cameras

Our review of the FXLION Nano ONE finds a tiny but capable V-mount option for shooters who need true portable power. It is for content creators, run-and-gun videographers, and travelers who prioritize low weight and multi-device charging; the single biggest reason to buy is its combination of a genuine V-lock mount in a pocketable 3.94 in x 2.79 in x 1.38 in package that still delivers 3400mAh (50Wh) of capacity and multiple outputs. The review emphasizes the battery's fast-charge options and versatile outputs that let a compact cine kit run longer without hauling full-size bricks.

Key Features

• Smallest V-lock form factor: The compact dimensions and 310g weight make it simple to carry as a spare power source without adding bulk to a camera bag.
• Multiple outputs: With a D-Tap socket plus USB-C, USB-A and micro USB ports, the battery can power a camcorder, LED light, monitor, wireless transmitter or smartphone directly.
• USB PD fast charging: The USB-C port supports PD up to 45W, which speeds charging of laptops and compatible devices when you need quick top-ups on location.
• Helpful status feedback: A 4-level indicator and OLED screen display remaining percentage, voltage and output information so you can manage runtime precisely during a shoot.
• Rapid recharge options: Using a V-lock/D-Tap charger the cell refills in about 2 hours, and PD Type-C chargers will recharge it in roughly 2.5-4 hours depending on wattage.

Who It's For

The FXLION Nano ONE is best for solo shooters, documentary filmmakers and vloggers who want an actual V-mount battery without the size and weight of standard bricks; its light weight and small footprint make it ideal for outdoor shoots and travel kits where space is limited. The multiple outputs and PD capability also suit hybrid shooters who mix a camera with LED panels, monitors or a laptop occasionally.

Those who need very long continuous run times for heavy pro cinema rigs should consider larger V-mount batteries instead, since 3400mAh is modest compared with full-size plates. If your workflow requires only a single USB output or you never use a V-lock, a simpler power bank might be a cheaper choice.

Pros & Cons

Pros

• Compact V-lock design gives real plate compatibility in a pocketable package.
• Multiple outputs including D-Tap and USB-C PD make it versatile for cameras, lights and laptops.
• Quick recharge options and an OLED screen provide useful runtime and status detail.

Cons

• At 3400mAh, capacity is limited compared with full-size V-mount batteries, so you may need two or more for long shoots.
• Not a replacement for high-capacity cinema workflows that demand extended continuous power from larger plates.
