Small, Practical and Universal
Good battery and charger. Not fancy, just effective and practical. Using this on an Einhell angle grinder which is far to demanding for this small battery unless I'm doing small jobs. Why did I buy it? Because it's universal so can be used in my other drills, strimmers, impact drivers and vacuum cleaners. It's now Spring 2026 and it's still going strong. Good value for money.

Einhell Power X-Change 18V, 4.0Ah Lithium-Ion: The Battery That Never Quits (Unlike My Wi-Fi)
If batteries had egos, the Einhell Power X-Change 18V, 4.0Ah Lithium-Ion would definitely be the cool, reliable one everyone wants at the party. This little powerhouse packs a punch, delivering solid, consistent power that makes you wonder how you ever lived without it. First off, the charge time—it’s like this battery has a secret life where it’s constantly working out. You’ll barely blink before it’s fully charged and ready to rock your tools like a pro. Whether it’s drilling, cutting, or whatever DIY madness you’re up to, this battery ensures you’ve got the juice to get the job done without constantly checking the charge like you do with your phone. Durability? Oh yeah, it’s built to last. You could probably throw it across the yard (but I wouldn’t recommend it), and it’ll keep going like the Energizer bunny, still full of energy and ready to go. It’s like the marathon runner of batteries—unfazed, unbothered, and always powering through. In conclusion, the Einhell Power X-Change 18V, 4.0Ah Lithium-Ion is the kind of battery you’ll want to take on all your DIY projects. It’s reliable, fast-charging, and ready to work whenever you are—basically the best team member you could ask for (except it doesn't need coffee breaks).

Easy to use great for block paving
Very impressed it works really well on my block paving no more back breaking with using a wire brush other bending..it takes abit of time but does a good job of getting rid of weeds and moss..Battery has not ran out so not sure how l9ng one charge lasts maybe an hour!..its easy to us and it's not heavy..ideal for any small paving gaps..its well made..the only down side is the handle is not that long so for anyone nearing 5ft 8in tall it would I think it would make them bend more when using it

Einhell 18V 4Ah battery and charger.
It was reasonably priced and quality is what you'd expect from a leading brand. It has a good battery life and isn't too heavy. It charges quite quickly too. It's great that it fits a multitude of Einhell tools

Charger comes with UK plug, and battery fits Einhell Power X-Change tools.
I have quickly discovered that the expensive part of battery-powered tools is the battery. It's sometimes cheapest to get a starter set with a drill, charger and batteries, even if you already have a drill! That's the route I decided to take, but my drill only had the 2AH batteries, and I wanted a bigger one for the circular saw I just bought. I didn't actually NEED a bigger battery as it turned out - these batteries are all pretty powerful, and I was able to cut through solid oak kitchen counter tops with the smaller 2AH batteries. The size has nothing to do with the available power, the only difference is that the bigger ones last longer. Nevertheless, it's useful to have plenty of batteries available. For jobs like kitchen fitting I've found that three is a good number - one in the drill, one in the impact screwdriver and one in the circular saw. Ideally another one in the charger... It gets expensive, which is why I made sure I got this in the sale. £40 for the battery and charger is not bad at all. I now have two chargers, which is always useful because I can have one in the workshop and one wherever I am working. From the older reviews it seems some came with an EU plug, but that seems to have been resolved now. My charger came with a UK plug on, so I was able to use it immediately. The battery had about 75% charge, so it didn't take long to fully charge it up. The charger has the usual lights to tell you if it's discharged, charging or full. The battery also has lights to tell you the charge status, which is handy. You just press a button next to the release catch. The battery only fits Einhell tools, officially. However, Einhell also make some of the tools sold by Lidl and Aldi, so you might find the batteries are interchangeable. The battery does NOT fit Makita, Bosch or Stanley Fatmax tools (old or new). You can get adapters... This 4AH battery is quite a lot heavier than the 2AH, which is worth remembering if you have to hold the thing over your head for any length of time. I guess that's why they make different sizes - use the right one for the job.

Mine came with a UK plug 👍🏻
I have 4 Einhell tools, 2 2a/hr batteries, and 1 charger. Needed another battery and, ideally, another charger, and thus seemed good value. Came same day which is perfect as I wanted the beefier battery for a job the day after. Delighted with it. Having read other reviews, I had a UK heavy duty plug ready to swap, but my charger came with a UK plug fitted. Excellent.

🛠️ Reseña: Einhell Kit de inicio Power X-Change – Batería de iones de litio 18V y cargador rápido He estado usando este kit con varias herramientas Einhell y la experiencia ha sido excelente. La batería de 4.0Ah ofrece buena autonomía y el cargador rápido permite tenerla lista en poco más de una hora. El sistema Power X-Change es muy práctico, ya que permite usar la misma batería en múltiples dispositivos. 🧩 Aspectos positivos: Batería de iones de litio de 18V con buena capacidad (4.0Ah) Cargador rápido, carga completa en unos 75 minutos Compatible con toda la gama Power X-Change de Einhell Indicador LED de carga en la batería y en el cargador Carcasa robusta con protección contra golpes y polvo ⚠️ Detalles a tener en cuenta: No incluye soporte de pared para el cargador El tamaño de la batería puede resultar voluminoso en herramientas pequeñas Precio algo elevado si se busca solo una batería de repuesto No es compatible con herramientas de otras marcas 💬 Comentario personal: Me ha parecido una inversión útil si ya trabajas con herramientas Einhell. La batería tiene buena duración y el cargador es eficiente. Ideal para quienes buscan versatilidad y autonomía sin depender de cables. El sistema Power X-Change realmente facilita el trabajo en distintos entornos.

Ho acquistato questo starter kit Einhell Power X-Change con batteria da 4.0 Ah e caricabatteria per utilizzare al meglio gli utensili della stessa linea. La batteria offre una buona autonomia e permette di lavorare senza dover ricaricare continuamente. Il sistema Power X-Change è molto comodo perché la stessa batteria può essere utilizzata su diversi utensili Einhell. Il caricabatteria è semplice da usare e ricarica la batteria in tempi ragionevoli. La qualità costruttiva sembra solida e affidabile. Per chi possiede già attrezzi Einhell compatibili, questo kit è una soluzione pratica per avere una batteria aggiuntiva sempre pronta. Nel complesso è un accessorio utile e ben fatto per il sistema Power X-Change.

Heb deze accu twee keer aangeschaft voor gebruik i.c.m. mijn Dyson stofzuiger. Met behulp van een verloopstuk (ook hier verkrijgbaar op Amazon) heb ik nu een oudere Dyson DC62 accu weer nieuw leven ingeblazen. De accu gaat veel langer mee dan de originele. Een tweede accu maakt het bovendien mogelijk te wisselen als de accu leeg is maar je nog niet klaar bent met stofzuigen :-) Er zijn meerdere opties voor de verlopstukken maar heb gekozen voor Einhell omdat deze accu's een grote capaciteit i.c.m. een gunstige prijsstelling. Bovendien: als ik nog accugereedschap aan wil schaffen kunnen deze accu's ook hiervoor gebruikt worden met andere Einhell apparaten (zeer uitgebreide range).
