Ryobi RP4700 Tek4 4V Charger Review
The RP4700 is the definite weak link in the Tek4 line of tools. This is the charger that comes with each of the battery-wielding tools (save the LED Flashlight and USB Portable Power Source). While small and convenient, the charger takes FIVE HOURS to charge a completely spent battery. Seriously? In what universe does it take 5 hours to charge a 4V Li-ion battery? Of the 12V and 18V tools we use the longest charge time we’ve seen is 60 minutes, and most 12V tools get done in around 30-40. There is really nothing to say about this charger except that if this is what it took to get Energy Star certification, then I think “going green” should only apply to the color of these tools.
