Short answer: the BC-W126S is Fujifilm’s desktop charger, AC 100–240V at 50/60Hz, supporting both NP-W126 and NP-W126S and filling an NP-W126S in about 150 minutes at +20°C. Because the X100VI, X-T50, X-E5, X-M5 and X half ship without a charger, there are three practical paths: buy the desktop charger, charge in-camera over USB-C with the power off, or use a cell with its own USB-C port. The most overlooked detail: Fujifilm states that in-body charging stops as soon as the camera is switched on.
Three charging paths compared
| Path | What you need | Speed / condition | Best for |
|---|---|---|---|
| BC-W126S desktop charger | Charger plus mains socket | About 150 minutes at +20°C; frees the camera | Multiple cells rotated overnight |
| In-camera USB-C | USB-C cable and adapter (cable supplied) | Camera must be off; charging stops when powered on | One-cell travel with minimal gear |
| Cell with built-in USB-C | Direct-charge battery | No camera or desktop charger needed | Skipping the charger, older bodies without USB charging |
The third path matters because the camera is not involved at all: pull the cell out, plug it into a power bank, and it charges. Our TNP-W126S direct-charge cell is rated 1050mAh, while the standard NP-W126S replacement is rated 1210mAh. Both fit the same bodies; only the charging inlet differs.
What the 150-minute figure actually means
About 150 minutes is Fujifilm’s rating at +20°C; the BC-W126 and BC-W126S are in the same range for their respective cells. It is not constant. Fujifilm gives a charging temperature range of +5–40°C and an operating range of 0–40°C, so charging in a cold car or after the camera has baked in the sun slows down or triggers protection. The original NP-W126S is rated 7.2V / 1260mAh with 8.4V maximum and about 47g — a modest cell, which is why 150 minutes is normal rather than slow.
Safety boundaries
Fujifilm’s compatibility chart adds three cautions: use a Fujifilm or correctly specified charger; an incompatible charger and battery combination can cause leakage, overheating or rupture; and in-body USB charging stops when the camera is switched on. The BC-W235 dual charger for the NP-W235 system needs a 15W+ PD adapter, but that belongs to a different battery family and its requirements should not be applied here.
Stop using any cell that swells, deforms or heats unusually. For long storage, Fujifilm recommends a dry place at +15–25°C rather than leaving a fully charged cell unused for months. More on heat and care is in the NP-W126S category.
Choosing by scenario
| Scenario | Suggestion |
|---|---|
| Shooting at home, already own a BC-W126 / BC-W126S | Add a standard cell, keep the existing charging setup |
| Travelling with one new body | One USB-C cable and off-camera hours, or a direct-charge cell |
| Two-day trip with three cells | BC-W126S overnight rotation; rely on quantity, not fast charging |
| Older body (X-T1 / X-Pro2) without in-camera charging | Desktop charger or a direct-charge cell |
FAQ
Can I use a phone charger with the camera?
A correctly specified USB-C supply works, but keep the camera off. Fujifilm states that in-body charging stops when the camera is on, and recommends a compatible charger.
Will the BC-W126S charge a plain NP-W126?
Yes. The official specification supports both NP-W126 and NP-W126S; they fit the same cameras, with the S version optimised for higher-draw bodies.
Why does charging take longer than 150 minutes in winter?
That figure is measured at +20°C. The official charging range is +5–40°C, and cold lithium cells charge markedly slower or trigger protection.
Can I shoot while the USB cable is plugged in?
You can leave it connected, but charging will not continue. For continuous power, use a DC coupler and external supply rather than USB top-up while shooting.
