Power and refills
Power and Refills
This is the group where a wrong purchase ends an appliance rather than merely disappointing you. Three of these items exist to move power, and the fourth is a consumable for a cleaning base. What they share is that each one arrives with a list of model numbers, and that list is the whole of what has been promised about it.
Stated and not stated
Stated by the listing
- A voltage figure, printed as a number.two of four listings
- The seller’s full list of the models the part is sold for.
- Whether the thing plugs into a wall, into an appliance, or into a cleaning base.
- How many pieces arrive in the pack.one of four listings
Not stated anywhere
- Whether the part suits anything at all outside that list.
- What the appliance in your hand expects, which is printed on the appliance.
- Whether the maker of the appliance has any involvement with this part.
- How long a charge takes, or how many charges a cell has left in it.
What the group is for
Core job
Replace a supply, a cable or a consumable without changing anything the appliance was built around.
Subgroups
15V chargers
one listing
A supply whose listing prints 15V. The figure leads its card because it is what decides whether the supply may be used at all.
5V chargers
one listing
A supply whose listing prints 5V. Same seller as the one above, appliances from the same maker, and no relationship of substitution between them.
Cables
one listing
A cable with no supply on the end of it and no voltage of its own. What it can charge depends entirely on what the other end is plugged into.
Cleaning refills
one listing
A consumable made by one company for a cleaning system built by another. The compatibility claim belongs to the cartridge’s listing, not to the appliance maker.
In this order
Buying order
- Buy nothing yet. Turn the appliance over, read what is printed on it, then read the label on the supply that came in its box. Those two lines settle the question, and neither of them is on this site.
- Match the voltage before anything else. It decides whether an appliance survives being plugged in, and no plug shape negotiates with it.
- Find your exact model in the seller’s list, character by character. A model that merely resembles yours is a different appliance with a similar name.
- Look at the connector last. It is the only part of this you can test by hand, which is precisely why it misleads people into checking it first.
- For a cleaning cartridge, read what the cartridge listing names and what the appliance documentation names, and buy only where those two agree.
Leave on the shelf
Skip these
- Any supply whose listing prints no voltage anywhere.
- A supply chosen because a model number looked close enough.
- A universal adapter with a bag of interchangeable tips, bought to solve a problem that one correct supply solves.
- A spare bought before the original has actually failed, which mostly buys you a drawer with something in it.
- A replacement head, foil or cutter that the appliance’s own documentation does not name.
Category cautions
The caution about voltage decides whether an appliance survives being plugged in. The rest decide whether the part was any use, which is a smaller loss and a far more common one. Three of the four below apply to every listing in this group. One is written for two listings.
- StopBefore any third-party power supply, read the voltage and the plug printed on the appliance itself or on the supply that came with it, and match both. A barrel that fits is not a match, and 15V into an appliance expecting 5V is a dead appliance.
- StopCompatibility is the list of model numbers a listing prints, copied and never extended. Two model numbers that share a prefix are a naming convention, not a statement that one part serves both.
- StopCharging happens away from the sink and the shower, with dry hands, and never while the appliance is still wet. A water rating describes an appliance in use, not an appliance connected to mains power.
- NoteReplacement foils, cutters and heads come from the list printed in the appliance’s own documentation. A part that seats is not the same as a part the maker names.
15V chargers

Cables
A cable, not a supply
Its listing describes a cable and prints no voltage anywhere, so what it can charge depends on whatever sits at the far end.

No voltage appears in this listing. That is not a shortcoming of the cable; it is the reason the question moves to the supply you intend to plug it into.

Cleaning refills

The only item here built by a company other than the one that made the base it drops into, which is where its claim starts and stops.

Last check
Before buying
The whole of this group comes down to a habit rather than a decision: read the appliance before reading the listing. Everything a seller can tell you here is a claim about parts you cannot see, while the one fact that governs the outcome is stamped in small print on something already in your bathroom. Find that first, and the rest of the page becomes a matter of matching characters.

The reasoning behind the figure on the card, and why a model list is a closed set.
- IPX and water
Why an appliance rated for water is still an appliance that charges in a dry room.
