What is NRG Bike Stem?
The NRG Power Stem is a Bicycle stem that replaces your existing stem to allow you to charge your device(s) on the go. With a weather resistant USB port and custom sealing cables included, the elements aren't going to prevent your tech from running out of juice when you need it the most. Patented, designed and manufactured in the UK, the precision machined aluminium Stem houses a fast charging power source with internal temperature cut out to prevent your NRG Stem from overheating.
