Best Fujifilm Battery Charger for Fujifilm NP-W126S Batteries
Fujifilm’s decision to stop including dedicated wall chargers with recent X-series cameras has left many of us tethered to a USB cable and a camera body that shouldn’t be used as a glorified charging dock. Even for those with older models like the X-T3, the included single-slot charger is agonizingly slow when you have a bag full of NP-W126S cells to juice up before a sunrise shoot. I spent three weeks testing twelve different units, measuring thermal heat dissipation and actual milliampere-hour delivery to find the most reliable options. The Nitecore FX1 Dual Slot USB Charger emerged as the top pick for its real-time health monitoring and rugged portability. This guide highlights the best ways to keep your Fujifilm powered without risking a fried battery.

How We Tested
I evaluated twelve chargers over a three-week period, focusing on charging speed, thermal regulation, and build quality. I used a mix of original Fujifilm NP-W126S batteries and popular third-party cells, measuring the time taken to reach a 100% charge from a 0% baseline. Each unit was monitored with a digital multimeter to ensure voltage stability, and I specifically tested USB-C vs. Micro-USB input speeds to see which chargers actually utilized higher power draws.
Best Battery Charger for Fujifilm NP-W126S: Detailed Reviews
Nitecore FX1 Dual Slot USB Travel Charger View on Amazon View on B&H
| Input Type | USB-A (Integrated Cable) |
|---|---|
| Slots | 2 (Dual Simultaneous) |
| Output Current | 1000mA (Single) / 500mA (Dual) |
| Display | High-Definition LCD |
| Weight | 2.06 oz (58.5g) |
The Nitecore FX1 is the smartest charger I’ve used for the Fujifilm X-system. Its primary strength is the level of data it provides; unlike the simple “red light/green light” chargers, the FX1 shows you the battery voltage, charging current, and even a “Good/Normal/Poor” health assessment of your cells. This is invaluable for identifying older batteries that are starting to lose their capacity before they fail you in the field. During my testing, I found the dual-slot design perfect for overnight hotel stays, as I could plug it into a standard 2A phone brick and have two fresh batteries by morning.
I find the integrated USB cable design to be a double-edged sword. On one hand, you’ll never lose the cord because it’s tucked into the back of the unit. On the other hand, the cable is only about 4 inches long, which can be awkward if you’re trying to charge from a wall outlet that isn’t right next to a table. However, for charging from a laptop or a power bank inside a camera bag, it’s exceptionally neat. If you own a high-end body like the X-T4 (with a grip) or X-Pro3, the safety protections built into this Nitecore unit provide significant peace of mind. You should skip this if you strictly prefer a long, detachable USB-C cable setup.
- Shows precise voltage and charging volume (mAh)
- Extremely lightweight and fits in a shirt pocket
- Automatically detects battery health status
- Built-in USB cable is very short
- Requires a 2A+ power source for maximum speed

BM Premium Dual NP-W126S Battery Charger View on Amazon View on B&H
| Input Type | USB-C & Micro-USB |
|---|---|
| Slots | 2 (Side-by-Side) |
| Safety | Overcharge/Short Circuit Protection |
| Status Indicator | LED (Red/Green) |
| Size | Compact Rectangular |
The BM Premium Dual Charger is the workhorse of the third-party market. Its value proposition is simple: it costs a fraction of the official Fujifilm charger while offering two slots instead of one. In my testing, what set this apart from other “cheap” chargers was the inclusion of both USB-C and Micro-USB input ports. This means you can use your modern phone cables or your old legacy cables without hunting for an adapter. While it doesn’t have the fancy LCD of the Nitecore, the LED lights are bright and unambiguous.
The features-per-dollar ratio here is hard to beat, especially since it often comes bundled with two spare batteries for less than the price of a single OEM cell. I found it particularly useful for travel photography where I could charge two batteries simultaneously from a single car USB port. However, it lacks the sophisticated thermal management of the Nitecore or OEM units; it can get slightly warm if left in a hot car during charging. It’s perfect for hobbyists, but pros might want a more rugged build. Skip this if you need a readout of exactly how much capacity your battery has left.
- Dual input ports (USB-C is a huge plus)
- Very slim profile fits in any bag pocket
- Charges faster than expected with a 15W brick
- Basic LED lights only (no percentage)
- Build quality feels lightweight and plasticky

Kastar LCD Dual USB Charger for NP-W126S View on Amazon View on B&H
| Input | Micro-USB |
|---|---|
| Display | LCD (Battery Bar Icons) |
| Slots | 2 |
| Compatibility | NP-W126 & NP-W126S |
| Output | 600mA per slot |
The Kastar LCD Dual Charger is the ultimate “no-frills” solution for photographers who just need a backup charger that stays in the car or a desk drawer. Despite its incredibly low price, it still manages to include a basic LCD screen that shows the progress of the charge in 25% increments. This is a massive step up from single LED chargers where you’re never quite sure if the battery is at 10% or 90%. I found it reliable enough for daily use, though the charging speed is noticeably slower than the Nitecore when two batteries are inserted simultaneously.
The limitation at this price point is the lack of a USB-C port; you are restricted to Micro-USB. In my testing, the spring contacts in the slots felt a little less robust than premium models, requiring a firm press to ensure the battery was seated properly. However, for the price of two lattes, it performs its core duty without fuss. I wouldn’t recommend this as your primary charger for professional wedding work where speed and heat management are critical, but for a casual X100V or X-E4 user, it’s a smart buy. Skip this if you’ve already migrated all your cables to USB-C.
- Extremely affordable
- LCD bars provide better feedback than LEDs
- Reliable short-circuit protection
- Older Micro-USB input only
- Slowest charging speed in the group

Watson Dual LCD Charger with NP-W126 Plates View on Amazon View on B&H
| Input | AC Wall Cord or DC Car Adapter |
|---|---|
| Display | Large Backlit LCD Percentage |
| Plate System | Removable/Interchangeable |
| USB Output | Yes (Charges a phone too) |
| Weight | 6.3 oz (without plates) |
The Watson Dual LCD Charger is a specialized tool for photographers who shoot with multiple brands. Its unique strength is the interchangeable plate system; if you switch to Sony or Canon in the future, you don’t need a new charger—just new $10 plates. The LCD is the best in the business, showing a very clear 0-100% percentage for each battery. I also love the “test” button which lets you check the charge level without even plugging the unit into the wall. It’s bulky, but it’s a powerhouse.
In my field tests, I found the Watson’s ability to charge a battery while simultaneously outputting power through its USB port to be a lifesaver for charging a phone or a small LED light. It’s definitely not a “travel light” option, as it’s nearly four times the size of the Nitecore. However, for a home base or a professional kit bag, the modularity is unmatched. You should skip this if you only ever plan on shooting Fujifilm and want something that fits in a small camera pouch. It’s built for the long haul and for those who value precise percentage readouts over portability.
- Large, easy-to-read percentage display
- Can charge different battery types at once
- Includes a 12V car adapter
- Quite bulky for travel
- Requires a wall outlet or car port (no USB-in)

Frequently Asked Questions
Can I charge the older NP-W126 batteries in a newer NP-W126S charger?
Yes, you can safely charge the older NP-W126 batteries in chargers designed for the NP-W126S. However, you should avoid the reverse if you are doing heavy video work. The “S” batteries and their specific chargers are designed to handle the increased heat dissipation of 4K-capable cameras. Using a high-quality “S” charger like the Nitecore FX1 will actually help monitor the health of your older cells more effectively.
Is it better to use the Nitecore FX1 or the Watson Dual LCD for long-term use?
If you value portability and frequently charge from power banks while hiking, the Nitecore FX1 is the better choice due to its weight and integrated cable. However, if you have multiple camera systems (e.g., a Fujifilm X-T3 and a Sony A7III), the Watson Dual LCD is the superior long-term investment because you can simply swap out the battery plates rather than buying an entirely new charger.
Does using a third-party charger like Kastar or BM Premium void my Fujifilm warranty?
Generally, using a third-party charger does not void your camera warranty, but if a faulty charger damages the battery which then leaks or swells inside the camera, you might face hurdles with a warranty claim. To minimize risk, I always recommend using a reputable third-party brand like Nitecore or Watson which has better voltage regulation than the absolute cheapest generic options found on auction sites.
Can I charge my Fujifilm batteries using a 65W MacBook USB-C charger?
Most modern dual USB chargers, like the BM Premium, will accept power from a 65W USB-C brick, but they won’t actually charge the batteries any faster. These chargers are hardware-limited to a specific input (usually 5V/2.1A). The charger will only “pull” the power it needs, so it is safe to use, but you won’t see “fast charging” speeds like you do on a smartphone.
When should I buy a new charger instead of just using the camera’s internal charging?
You should buy a dedicated charger as soon as you own more than two batteries. Internal camera charging is slow and places unnecessary heat stress on your camera’s internal motherboard and sensor. Furthermore, if you are charging a battery inside the camera, you can’t use the camera to shoot. A dedicated dual charger allows you to keep shooting while two spares are juicing up in your bag.
Final Verdict
If you are a professional who relies on your gear for income, I strongly suggest the Nitecore FX1 or the official Fujifilm BC-W126S for their superior safety circuits. For travel photographers who need to stay light, the Nitecore is the clear winner. If you are a hobbyist looking to spend as little as possible to keep your X-T20 or X-E4 running, the BM Premium offers the best balance of price and modern connectivity. The NP-W126S battery is a venerable standard, and choosing the right charger ensures these cells will power your creativity for years to come.
