K&F CONCEPT 4-Slot Battery Charger Case with Max 45W PD Fast Charging (NP-FZ100/LP-E6 compatible)
Product description
If you regularly shoot with Sony NP-FZ100 or Canon LP-E6-series batteries, a multi-bay charger that also keeps spares tidy can make life a lot easier. This K&F CONCEPT 4-slot battery charger case is built around that practical idea: charge up to four compatible batteries at once, and store memory cards in the same case so they’re less likely to get lost in the bottom of your bag.
That said, it’s not a “one charger for everything” solution—battery types are tied to the internal contact layout, and it only makes sense if your kit matches the listed battery families.
The essentials
This charger case is designed for NP-FZ100 batteries (Sony) and LP-E6/LP-E6NH/LP-E6P/LP-E6N batteries (Canon). The case includes four charging slots plus built-in memory card storage: 2 Type-B card slots and 2 Type-A/SD card slots. The internal slots are labelled, and each slot uses two different sets of contacts—so the case is meant to guide you to the right placement for the specific battery model.
On the charging side, it supports Type-C PD fast charging as an input, with a maximum total charging power stated as 40W (even though the product name mentions Max 45W PD fast charging). The charger can run all four channels independently when enough power is available.
What you’ll notice in everyday use
The biggest day-to-day win is convenience. Instead of carrying batteries loose and charging them one by one, you can load up to four batteries into the labelled slots, plug in via USB-C PD, and glance at the LED indicators for progress.
There’s also a simple “sort your bag” benefit: memory cards have their own place inside the case, which can help prevent the usual scenario where you’re at a shoot and you’re digging for a card you’re sure you packed.
A small but important detail: the internal labelling and contact setup means you should follow the slot instructions rather than trying to “make it fit”. It isn’t the kind of charger where trial-and-error is a good strategy.
Charging performance and power behaviour
On paper, the charging logic is clear and fairly flexible, but it depends on your power adapter.
- The charger uses a Type-C PD fast charge input and states a maximum total charging power.
- Power level affects how many charging channels activate at the same time.
- It can charge 4 batteries independently.
The more power you feed it, the more simultaneous charging channels you can use. The manufacturer also notes that you should use at least a 40W power adapter to ensure proper battery charging.
If you only ever use a low-watt USB-C adapter, you may find it “works”, but it could end up activating fewer channels and charging less quickly than you’d expect.
LED smart display you can actually read
The included LED indicators show battery charging level progress at 25%, 50%, 75%, and 100%. A solid light indicates a fully charged battery, while a flashing light means charging is in progress.
This is the kind of indicator set that suits real-world use—no app, no cables to manage beyond the power lead, and you can check status at a glance while packing up.
Safety and portability
The charger case includes multiple protection features to cover common charging risks, including over-voltage protection, over-current protection, short circuit protection, high-temperature protection, and over-charge protection.
For transport, the “case” format is doing more than looks. It’s intended to keep both batteries and memory cards organised in one place, which is handy for travel and quick turnarounds between shoots.

- Power adapter guidance: use at least a 40W power adapter for proper charging
Who it suits (and where it may fall short)
It makes sense if you want one organised charging/storage case for a mixed Sony or Canon kit that uses NP-FZ100 and LP-E6-series batteries. If you shoot in short sessions and like to keep your cards protected (and your spares accounted for), this is exactly the kind of accessory that earns its keep.
You may want to skip it if:
- Your batteries are not NP-FZ100 or LP-E6-series, because slot contacts are designed around those specific models.
- You don’t have a suitable Type-C PD adapter and tend to rely on basic chargers—lower power can reduce how many charging channels activate.
- You’re after a “set-and-forget” charger that charges your batteries quickly regardless of your adapter situation, this one is more dependent on feeding it the stated power.
Buying verdict
It’s a sensible purchase if your camera setup uses NP-FZ100 and/or LP-E6-series batteries and you want a charger case that also holds memory cards. The labelled slots, multi-bay charging, and LED progress indicators are practical touches, and the built-in protections are the sort of details you’d expect from a charger you’ll use regularly.
It might not be the best choice if you only need a basic single-bay charger, or if you’re unlikely to use a 40W (or higher) Type-C PD adapter, because the charging performance depends on that.
Mini FAQ
Does it charge four batteries at the same time?
It’s designed to charge 4 batteries independently, but the number of active charging channels depends on the power level supplied via the Type-C PD input.
What memory cards can it store?
It includes built-in storage for 2 Type-B cards and 2 Type-A/SD cards.
How do I know what slot to use for my battery?
The slots have two sets of contacts and each compatible battery model is labelled inside the slots, so you should place the battery according to the model indications.
Do I need a special power adapter?
For proper charging, it’s recommended to use at least a 40W power adapter.
Is it compatible with Sony A7 models and Canon EOS R bodies?
The compatibility list provided includes Sony A7iii/A7iv and several other models, and Canon EOS R5/R6/R7 and related variants listed in the description.
