Using it to power my Celestron telescope. Works very well when other power sources are not available and eliminates the need for a continuous supply of AA batteries. Small and non-obtrusive but gets the job done. I would recommend it to any one with similar needs
I charge this thing and off I go. I use two of these to power a Night vision camera and monitor. These cells will run all night long. I might buy a couple more for back-up
I am using this with a small VHF receiver and it appears it is injecting noise into the receiver. I placed some toroids on the power line to get rid of the noise. For most users this would never be of any consequence. Otherwise seems like a good unit.
