Our Verdict

This is a very simple to use, handy torch that fit right on you your keyring, so you will always have the torch on you. The K4R has 3 power settings 20 lumens, 80 and 120. The torch is very simple to carge you dont even need and additional cable, the torch plugs strait in to a USB port. This wouldnt be me dedicated light source, but its a handy back up on the trail, and if used just at home its almost limitless how often the K4R will come in handy.
