New Colorado company will rent out phone chargers when patrons’ phones die at bars

We’ve all been there. It’s 11 p.m., you’re three drinks into a Saturday night, and your phone is at 4 percent. No Uber. No Venmo. No way to text the group chat you wandered away from 45 minutes ago. You are, for all practical purposes, stranded in 2004.

Enter Massive Technology, a Denver startup founded by three friends, Sean Hyatt and married couple Matt and Kristin Reiswig, who are putting portable phone charger rental kiosks inside bars and clubs around the city. The concept is simple: download the ChargerGoGo app, grab a charger from the kiosk, pay $6 for the first hour of fast-speed charging and $2 for each additional hour after that. Average rental time so far? Just 46 minutes, roughly one more round and a bathroom trip. You can return the charger to any kiosk in the network, keep it overnight if you’re stumbling home, or buy it outright for $45. If you forget to return it, that’ll cost you $15 per day.

Hyatt, who was raised in Aurora and got his MBA from Metropolitan State University, said he and the Reiswigs got the idea after renting portable chargers on a trip and realized Denver’s bar scene was wide open for the concept. They launched in February 2026, and Massive Technology is now the largest local distributor for ChargerGoGo, a Las Vegas-based company with 6,000 stations nationwide, with 27 kiosks in 25 Denver bars and clubs, including The Church and Charlie’s off Colfax. The kiosks are free to the venues that host them, and the biggest unit, a 32-battery beast that cost $5,500, lives at Club Vinyl at 11th and Broadway.

The trio has invested $30,000 to get the business running without taking on any investors, and Hyatt says revenue has doubled every month since launch, mainly through better signage and advertising on the kiosk screens. Eight of the 27 machines have already been paid off. “We make money either way,” Hyatt said of the chargers. “We don’t care if they return it or not.”
