Thank you very much for this idea.
I ordered one and two batteries. My biggest problem was that I got through the day OK and at night, when I sat down to relax - Beep - Red light - done for the day.
With the Ryobi TEK4 - I just plug it in to my streamer and relax.
Another bonus is that it comes with a full set of adapters and will do the same for my phone if need be or most any USB powered device.
Thank you again.
