An adapter has a direction. One that runs a Makita tool on a Parkside battery does not do the reverse: that takes the other model. None of these adapters is made or approved by the brands involved.
The full matrix
The battery you own, by row; the tool to power, by column. A hatched cell: people search for the pair, but no listing confirms the direction.

Before you buy one
An adapter cuts the conversation between battery and tool. Protection against overheating and deep discharge then rests on a third-party housing. It also voids the warranty on both the tool and the battery.
Never on a cutting tool
Circular saw, reciprocating saw, chainsaw: losing power mid cut is not an inconvenience, it is an accident.
Never at height
On a ladder or scaffold, a tool that stops or restarts on its own puts the balance of the person holding it at stake.
Not for continuous heavy load
Rotary hammer in concrete, grinder, mixer: that is where the battery heats most, so where its protection matters.
A reasonable use: work light, fan, shop vacuum, USB charger. Low-current devices, set on the ground, kept in sight.
Why these adapters sell
A tool battery costs between a third and half of the bare tool. Someone with four Parkside packs who wants a machine Parkside does not make has two choices: buy another brand's batteries, or buy an adapter. Parkside is in fact the most searched starting battery: it is the cheapest platform, the one owners want to leave without writing off what they paid.
How we built this list
This list is the result of our own research. We identified the brand combinations DIYers look for most, then checked for each one that an adapter really exists in the right direction, from its reference and description: MT18EIN, for instance, is an adapter for a Makita battery to an Einhell tool. Where we found no reliable adapter, the page says so rather than pointing you to a near miss.
Frequently asked questions
Can an adapter damage my battery?
It can let the battery discharge too deeply or heat up without the tool cutting out, because the electronics that let battery and tool talk no longer pass through. Recent lithium packs have their own protection, but it was not designed for another brand's tool.
Does an adapter void the warranty?
In practice, yes: makers exclude damage caused by accessories they did not design, which covers both the battery and the tool.
Adapter or genuine battery?
For a tool you use often, for cutting or for work at height, the genuine battery of the tool's brand. An adapter makes sense for a low-current extra device, when buying a battery would cost more than the device itself.
