USB LED Dual Battery Charger for BN-VF808/BN-VF815/BN-VF823 Series
Product description
What this is
A compact USB-based charger designed to power multiple Nikon-style BN‑VF batteries, including BN-VF808, BN-VF815, BN-VF823 and their variants. It’s a practical accessory for camera setups that rely on swapable, rechargeable packs, offering a simple way to keep spares topped up via a USB source.
How it works
The charger plugs into a USB power source and delivers charging current to two batteries simultaneously. It uses automatic constant current control to manage charging, aiming to prevent overcharging, short circuits or electrical shocks. An LED indicator provides a quick visual status of the charging process.
Key specifications (as provided)
Input: 5V, 2–3A, Output: 8.4V, 700mA per channel when charging two cells. Size roughly 4.5 x 3.75 x 0.75 inches and weight around 3.8 oz. The unit relies on USB power rather than a dedicated wall adaptor.
What stands out in day‑to‑day use
If you frequently shoot with a battery‑swap workflow, this charger’s dual‑bank design can save time by charging two batteries at once. The USB input makes it convenient for travel, especially when you have a portable power bank handy. The LED indicator is a small but useful cue to know when a pack is ready, which helps minimise camera downtime.
What may give you pause
On paper, the charger delivers a steady 700mA per cell, but real‑world performance can vary with the USB source quality and cable. There’s no mention of a dedicated travel case or additional safety features beyond basic current control, if you regularly rely on rugged or pro‑grade peripherals, you might want to verify compatibility with your existing kit.
Who it’s for
This is likely a sensible option for hobbyists or semi‑pro users who use BN‑VF808/815/823 batteries and need an inexpensive, compact USB charging solution for travel or on‑set use. It may suit shooters who prioritise convenience and value over a premium, feature‑rich charger.
Who it isn’t the best option for
If you require a charger with extensive safety protections, faster charging, or a rugged build, this unit may fall short. It also isn’t a stand‑alone power solution for other battery formats, and there’s no explicit information about supported charging cycles or temperature management beyond automatic current regulation.
When it makes sense to buy
Consider this charger when you need a straightforward, USB‑powered two‑bay charger that works with BN‑VF batteries and you want to reduce cable clutter on location or in the studio. It’s a practical add‑on if you already charge through USB devices and want a single source for two batteries.
Before you buy, check
- Ensure your USB power source can supply 5V with sufficient current for dual‑bay charging (ideally a solid 2–3A supply).
- Confirm the exact BN‑VF battery variants you own are compatible with this charger’s two‑bay design.
- Consider the charging speed relative to your needs, two at once at ~700mA each is workable for routine shoots but not blazing fast.
Practical usage example
Imagine a small shoot where you’ve got two BN‑VF823 batteries on the charger while you film with a mirrorless body. When one battery runs down, you swap it in and still have the other charging, keeping you rolling with minimal downtime. The LED gives you a quick read on status during a busy day.
Final decision
Should you buy it?
It makes sense if you prioritise practical, value‑oriented charging for BN‑VF batteries and you’re comfortable with USB power solutions. It’s probably not ideal if you need lightning‑fast replenishment or advanced safety features.
