SmallRig EN-EL15c Battery Charger (Dual Slot) with 22.5W USB-C for Nikon Z & D series

What it is and why you’d want it

If you shoot with Nikon cameras that use EN-EL15c batteries, you’ll quickly end up thinking about charging as much as you do about shooting. The SmallRig EN-EL15c Battery Charger is a dual-slot charger designed to top up one or two EN-EL15c batteries at the same time, with a USB-C charging setup intended for flexibility away from home.

On paper, it’s built for real-world routines: keep a spare battery ready for early starts, long sessions, or when you don’t want to be tied to a single wall socket. The 22.5W USB-C port and included fast charging cable aim to make it simpler to power the charger with common adapters or portable power options.

Key takeaways (the stuff you’ll notice)

The headline features are practical rather than flashy. You get a dual-slot design, a power display with LED indicators per slot, and safety monitoring to help manage temperature and voltage during charging.

Where it stands out is the combination of convenience (dual slot + USB-C input) and a clearer charging status. Each slot has 5 LED indicators, where each light represents 20% of battery level, and a red warning light is used for critically low battery situations. That’s the kind of detail that reduces guesswork, especially if you’re swapping batteries mid-session.

That said, it does rely on EN-EL15c specifically. If your kit uses a different Nikon battery type, this won’t be the right match—worth checking before you commit.

The charging experience in everyday use

The dual-slot approach is the reason many people consider a charger like this. If you have two EN-EL15c batteries, you can charge them simultaneously, or charge just one when you only need a quick top-up.

The listing states that it can fully recharge two EN-EL15c batteries in approximately 2 hours. In real shooting terms, this is the sort of turnaround that can matter if you’ve got a morning shoot, then need a second battery ready for afternoon use.

You’d also likely appreciate the LED indicators while you’re planning your next switch. Instead of waiting around with no feedback, you can gauge the remaining level, and the red warning light is meant to remove the “is it nearly empty?” uncertainty.

Tech specs (as far as the listing shows)

• Type: EN-EL15c battery charger for Nikon cameras
• Charging design: dual-slot, simultaneous charging of two batteries or single-battery charging
• Stated rapid charge time: approximately 2 hours to fully recharge two EN-EL15c batteries
• Power input: USB-C (universal), with stated 22.5W fast-charging capability
• Display: 5 LED indicators per slot (each representing 20% battery level) plus a red warning light for critically low charge
• Safety functions: over-temperature protection, over-voltage protection, reduced charging speed when overheating is detected, charging stops on over-voltage, and trickle charging mode as the battery nears full

What stands out vs simpler chargers

If you’re comparing this type of product against more basic chargers, the main differentiator here is the USB-C input paired with a fast-charging capable port. That’s useful if you’re likely to travel with a portable power source, or if you prefer the flexibility of USB-C powering rather than relying purely on one fixed charger setup.

The dual-slot design also changes how you manage spares. Many photographers don’t just charge “when they remember”, they cycle batteries. Having two slots makes it easier to keep a pair topped up, rather than planning around single-battery downtime.

It’s not a perfect fit for everyone, though. If your routine only involves one battery and you never charge on the move, you may find you’re paying for features you won’t use.

Limitations and what to check before buying

Before you buy, there are a couple of practical checks that avoid headaches:

• Compatibility is for EN-EL15c batteries. The description also lists support for a range of Nikon models (including Z and D series listed in the listing), but the battery type requirement is the key.
• The charging time is described as “approximately” for two batteries. Real results can depend on conditions, but the listing figure is still a useful expectation.
• You’ll want a compatible power setup for USB-C charging (the listing notes it can be powered via wall adapters, car chargers, or portable power banks, but you should still ensure your chosen adapter/power source is suitable).

There’s also a small, design-level note: the charger uses a semi-enclosed design intended to help prevent batteries from slipping out and to protect against scratches. That’s reassuring for day-to-day handling, but it’s still a charger, so keeping contacts clean is sensible like with any battery system.

Who it’s for, and who should look elsewhere

It makes sense if you:

• Use EN-EL15c batteries regularly and want the option to charge two at once.
• Prefer USB-C charging for flexibility when travelling or when you don’t want to hunt for the “right” wall adapter.
• Like the idea of per-slot LED level indication so you can plan battery swaps more confidently.

It may not suit you if:

• Your camera uses a battery type other than EN-EL15c.
• You only ever need one battery charged occasionally, and you’d rather pay less for a simpler single-slot option.

What’s included (based on the listing)

The listing indicates it includes a fast charging cable alongside the charger, and it’s described as being powered via common charging sources such as wall adapters, car chargers, or portable power banks when using USB-C.

Is it worth it?

Worth considering if your Nikon setup uses EN-EL15c batteries and you want a dual-slot charger with USB-C fast charging and clear LED status per slot. The stated ability to fully recharge two batteries in around 2 hours is a genuinely useful target for people who shoot in bursts and swap spares.

However, don’t buy it if your batteries aren’t EN-EL15c, and keep expectations grounded if you’re seeking a single-purpose, minimal charger. For most photographers running a spare-battery workflow, this feels like a sensible mid-range practical tool rather than an extravagant gadget—especially if USB-C convenience matters in your day-to-day.

Mini FAQ

Does it charge one battery or two?

It’s a dual-slot charger, so you can charge two EN-EL15c batteries simultaneously, or charge a single battery in one slot.

How do you check battery level?

Each slot has 5 LED indicators, with each light representing 20% of battery level, plus a red warning light for critically low battery situations.

Can it be powered without a wall socket?

The listing says it can be powered using wall adapters, car chargers, or portable power banks via its USB-C input.

What safety features does it include?

The charger is described as having over-temperature protection and over-voltage protection, including reduced charging speed when overheating is detected, stopping charging on over-voltage, and trickle charging near full.

Is this compatible with Nikon Z and D cameras?

The description lists support for a range of Nikon models in addition to EN-EL15c compatibility, but the battery type requirement (EN-EL15c) is the foundation to check first.
