### ⭐⭐⭐⭐⭐ Powering Up Anywhere with Tonsim Adapters
*by O***M on 29 April 2024*

As a longtime Dewalt user, I'm always on the lookout for accessories that enhance the versatility of my tools. The Tonsim Adapters for Dewalt Battery have quickly become one of my favorite additions to my toolkit.What impresses me most about these adapters is their unmatched versatility. Whether I'm camping in the wilderness or working on a DIY project in the garage, I can rely on my Dewalt batteries to power a wide range of devices and appliances, thanks to these adapters. From charging my phone to inflating air mattresses, the possibilities are endless.I also appreciate the simplicity of their design. There's no need for complicated setups or technical expertise—all it takes is a quick plug-in, and I'm ready to go. Plus, the durable construction gives me peace of mind knowing that these adapters can handle whatever I throw their way.Of course, like any product, these adapters have their limitations. They're designed specifically for Dewalt batteries, so users with other brands may need to look elsewhere for compatibility. Additionally, certain devices may require additional adapters or converters for proper functionality. However, for Dewalt users looking to make the most of their battery collection, these adapters are a must-have accessory.

### ⭐ Rubbish
*by M***  on 3 March 2025*

Absolute rubbish, battery fully charged up and it doesn’t work at all

### ⭐⭐⭐⭐ Works well, decent power output
*by R***W on 23 January 2024*

Works well, decent power outputThis adapter allows your Dewalt 18V or 20V battery to power 12V devices that might plug into your car, via a standard cigarette-lighter / accessory socket.It could be useful for car or caravan accessories such as fridges, vacuum cleaners and tyre compressors *however* do please be aware that Dewalt batteries are not necessarily designed to be providing power for a long period of time. Although it's not going to harm your batteries, I would be doubtful (as an example) that a single Dewalt battery is going to power a fridge for any sustained length of time.The measured output voltage was 12.65V which is perfectly acceptable (a car battery output typically varies between 12 and 14V) and the claimed 12A capacity will be useful.At the right price this could be a useful adapter.
