USB Dual Camera Charger for EN-EL14 / EN-EL14a Batteries ( Nikon D series and Coolpix )

What it is and what it does

This USB dual charger is designed to power up EN-EL14 and EN-EL14a batteries used across a range of Nikon cameras, including models in the D3500, D5600, D3300, D5100, D5500, D3100, D3200, D5200, D5300, D3400 lines and the DF, as well as Coolpix P7000/7100/7700/7800 series. It brings battery charging into the real world by plugging into a USB power source, so you can top up your spares on the go or in the studio without needing a dedicated wall outlet.

How it works and what to expect

On paper it uses automatic constant current control to help prevent overcharging, as well as short circuits and electronic shocks. The LED indicator gives you a straightforward read on whether a battery is charging or complete. The charger is built with updated charging circuitry and automatic voltage regulation to suit standard 5V USB inputs and a typical 8.4V output at 700mA per bay. In practice, this means you can charge two EN-EL14/EL14a batteries at once from a portable power bank or a laptop, which is handy when you’re travelling or shooting away from mains power.

Pros and what stands out

• Convenience: charges via USB, so you can power it anywhere with a USB source.
• Dual a bay design enables two batteries simultaneously, saving downtime between shoots.
• Practical indicators: a smart LED shows charging status, aiding quick checks on the go.
• Safety features: designed to minimise the risk of overcharge, short circuits and shocks.

Limitations and who it’s for

• It’s not a replacement for a dedicated Nikon charger if you rely on max throughput or specific Nikon charging routines, the stated output is 700mA per bay, which is reasonable for spares but not the fastest option in some setups.
• Since the data is limited to generic specifications, real-world performance may vary depending on the USB source and cable quality.
• Not all EN-EL14/EL-14a variants or future battery chemistries are guaranteed to be supported beyond the listed models.

Is it worth it for you? practical scenarios

• If you travel a lot or work with multiple bodies, this charger offers a compact, USB-powered solution to keep batteries topped up.
• If you primarily shoot in studio with reliable mains, you might prefer a dedicated wall charger with possibly faster charge times.
• If you usually rely on a single battery, it may still help as a backup or to reduce downtime between sessions.

What to check before buying

• Ensure your USB power source can provide enough current for two bays concurrently (the product lists 5V 2-3A input).
• Check that your camera models are within the supported EN-EL14/EL-14a family listed.
• Consider cable quality and USB port stability, as these can influence charging consistency in mobile setups.

Practical use case in real life

Imagine you’re on a weekend shoot with two bodies. You slip this charger into a small bag, connect it to a portable USB power bank, and swap batteries between cameras while continuing to shoot. The LED indicators give a quick visual cue to know when each battery is ready to go back in the camera, so you don’t waste time waiting for a wall socket.

FAQ

• Can I charge two batteries at the same time? Yes, it supports dual charging.
• Do I need a special USB charger or cable? A standard USB power source is compatible, but using a stable, adequately powered USB supply is advised for consistent charging.
• Is it safe for long-term use? It includes automatic current control and safety features, however, always monitor charging cycles and avoid leaving batteries on charge unattended for extended periods.

Final verdict

Is it worth it? Worth considering if you need a compact, USB-powered dual charger for EN-EL14/EN-EL14a batteries and you prioritise flexibility and portability over the fastest possible charge. It suits photographers who travel light and want a straightforward backup charging option, it may be less ideal for those who demand maximum charge speed or have batteries outside the supported model list.
