Choosing an NP-FZ100 charger comes down to three questions: does the spec match (output voltage and connector), is the speed enough for your rhythm, and is this charger staying on a desk or travelling with you. An original charger is the low-effort option for compatibility and stability, but it usually costs more and typically handles one pack at a time. Third-party chargers are cheaper and come in more shapes, including dual bays and USB input. USB chargers win on travel because they share a brick and cable with your phone and run off a power bank. For most people the sensible combination is a stable desktop charger at home or in the studio, plus a USB charger in the bag.
Three Approaches Compared
| Factor | Original charger | Third-party charger | USB dual charger |
|---|---|---|---|
| Price | Sold at a premium | Comparatively low | Comparatively low |
| Packs at once | Usually single bay | Single or dual bay | Mostly dual bay |
| Power source | Mains | Mostly mains | USB — brick, power bank, car adapter |
| Travel | Needs a mains plug | Needs a mains plug | Shares your phone brick |
| Indicators | Clear | Varies by brand; see reading the indicator lights | Varies by brand |
| Suits | Those who want the original experience | Value and multi-bay needs | Travel, outdoor and car use |
That table compares types, not individual products. Charge current, whether there is a display, and fast-charge protocol support all vary by model, so read the stated output figures before buying.
The Cost Arithmetic: Kits Usually Win
Here is the actual price structure. YO’s NP-FZ100 compatible battery is about $17.89 on its own, about $22.93 for one battery with a charger and about $36.74 for two batteries with a charger. In other words, adding a charger costs roughly $5, which is hard to match buying one separately, and it removes the risk of a spec mismatch. The TNP-FZ100, at 2400mAh / roughly 17.3Wh, runs about $19.66 for a single pack, about $24.70 with one charger and about $39.92 for two batteries with a charger.
If the camera came with one battery and you want a charger as well, take the one-battery kit. If you already have two packs but only one charger, or you are kitting out from scratch, the two-battery kit works out cheaper on total spend.
Picks by Scenario
- Charging at home, not in a hurry: a plain single-bay charger. Prioritise stability and pull the pack once the light goes green.
- Two or three packs a day: a dual-bay charger changes the workflow noticeably; sizing is in multi-bay chargers for four packs a day.
- Travel, outdoors, in the car: a USB-input charger runs off your phone brick or a power bank and cuts the number of things you carry.
- Body supports USB power: you may be able to charge through the camera’s USB-C port and leave the charger at home; the trade-offs are in charging through the body's USB-C port.
- Long video takes: no charger solves continuous supply. Look at a dummy battery with an AC adapter instead.
What to Check Before Buying
- Output voltage and connector: the listing should state NP-FZ100 compatibility, with matching voltage and polarity.
- Charge current: more current means faster and hotter, so routine current is the safer everyday choice.
- Clear indicators: at minimum you need to tell “charging” from “done”. Ambiguous light language causes unnecessary grief.
- Bay and spring quality: springs should hold the pack firmly. Poor contact is the usual reason for a flashing red light.
- Protection: over-charge, over-current and short-circuit protection are table stakes. Be cautious of listings that do not mention them.
- Portability: if you travel often, folding prongs and a shape that slips into a side pocket are worth having.
Using It Well
- Charge on a hard, flat, ventilated surface. Not a bed, not inside a camera bag.
- On a multi-bay unit, leave space between packs. Do not stack chargers or cover them.
- A pack fresh out of the camera is warm. Give it a few minutes first.
- Let it go green before unplugging, instead of interrupting the bulk phase.
- If the charger shell is hot, smells or buzzes, stop using it.
FAQ
Will a third-party charger damage my batteries?
A spec-matched unit with protection circuitry is normally fine. What actually damages cells is long storage at full charge in heat and repeated deep discharge — the charger is only one factor.
Can I run a USB charger from a fast-charge brick?
Yes, but the charger’s own input rating sets the ceiling. A brick rated far above it will not speed things up much and may simply add heat.
How many chargers do I need?
One fixed at home and one in the bag covers most people. If you regularly charge three or four packs at once, look at a multi-bay unit.
Is the original charger worth it?
If you value the original experience and the budget is there, it is a reasonable buy. Most people are well served by the charger that comes in a kit.
If you would rather not spend an evening comparing chargers, take a matched kit. YO’s NP-FZ100 is about $17.89 for a single pack, about $22.93 for one battery with a charger and about $36.74 for two batteries with a charger — the charger adds roughly $5. The TNP-FZ100 at 2400mAh runs about $24.70 with one charger and about $39.92 for two batteries and a charger. Studios and rental houses kitting out packs and chargers together should go through wholesale enquiry, where orders over 100 units are quoted per batch.
