Bosch GAA12V-21N 12V Max Portable Power Adapter

Works as shood!

Must have you have Bosch tools, but one of these you could keep your phone charged

Works great thank you!

Cannot charge at all. It turns off immediately. And if you don't register as a user, the warranty will not be extended. I buy a lot of BOSCH products and I don't want to have to register every time. Worst.

This is an awesome battery power bank. I use this almost everyday to keep my phone charged and it's perfect because I'm never tied to a wall waiting for it to charge. What I really like is I already have the batteries and drill batteries charge way faster than my other power banks. I highly recommend this product.

I don't have the jacket this is intended for. Instead, I use it to test LED strip lights, cameras, trailer lights, and other 12V accessories. I've made a few adapters and it's part of my travelling toolbox. It's way more convenient than carrying around a power supply and extension cord.

I like Bosch tools and own their 12v and 18v tools, but this one is not their best effort…This charger lacks a led light that tells you it is working or a battery level meter to tell you if battery is full or not. With battery in and wire connected to device you are attempting to charge (phone for example), you still need to push a red button to get it working, but there is no light or any mechanism to tell you it is turned on.

I have some 12v Bosch tools, with several batteries. I used this adapter to plug in a green fishing light to attract fish at night. Certainly not it's intended use, but it works great for me. Lightweight and very portable compared to other battery options.
