A new component brand has designed a stem with a built in power bank, that can charge your devices with a universal USB port.
The NRG Stem is made out of heat-treated 6061 aluminium, and there's an LED light indicator on the top to show you howe much charge you have remaining. A rubber cap fits over the top of the USB ports when not in use. The port interface can also be used to charge up the stem itself, so as long as you've got a long enough cable, you won't have to keep removing it to keep it charged. It means you can keep your GPS, lights and phone amongst other things topped up on the go without having to worry about running out of juice. There are two lengths, 93mm and 103mm, with battery capacities of 2700MaH and 3500MaH respectively.
Although it's the first time we've seen charging via a stem, it's not the first instance of USB integration on a bike: way back in 2011 we reviewed the Tout Terrain touring bike that had a USB port fitted under its headset via a dynamo adapter, and Dave reviewed the Igaro D1 Mod 5 USB converter for dynamo hubs in December - but on first impressions the NRG stem looks like a wire and hassle-free solution, so we'll be following its development with interest.
We don't have pricing information for the NRG Stem yet, but they're now taking pre-orders. Check out their website here to sign up for more info and/or register for a pre-order.
After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He joined road.cc in 2017, having previously worked for 220 Triathlon magazine. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
