About J+ Booster: Swiss-Engineered EV Charging for North America
J+ Booster is the North American face of the Juice Group, a globally respected Swiss producer of electric vehicle charging solutions. Operating under J+ Americas Inc. and headquartered in St. Petersburg, Florida, the brand brings premium European engineering to EV owners across the United States and Canada. With a global team dedicated to innovation and sustainability, J+ Booster has carved out a unique position in the EV charging market by delivering industrial-quality portable chargers that work equally well at home, in the workplace, or deep in the backcountry.
The J+ BOOSTER 2: One Charger for Every Situation
The flagship product — the J+ BOOSTER 2 — is a portable Level 1 and Level 2 EV charger engineered specifically for the North American market. Built from military-grade aluminum, it withstands wheel loads up to 6,600 lbs and carries an IP67 rating, meaning it is fully waterproof and dustproof for reliable performance in any climate or condition. Weighing just 2.2 lbs without cables and accessories, it is designed to travel with you without slowing you down.
What sets the J+ BOOSTER 2 apart from conventional home charging stations is its flexible, adapter-based architecture. The unit supports adjustable amperage settings across a wide range, allowing EV owners to tailor their charge rate to the available power source — whether that's a standard household outlet or a 240V commercial receptacle. The charger automatically detects the connected adapter type and optimizes power output accordingly, eliminating guesswork and manual configuration.
Safety, Certification & Build Quality
For EV owners who take safety seriously, J+ Booster's commitment to certification is notable. The J+ BOOSTER 2 is ETL-certified to UL 2594, UL 2231-1, and UL 2231-2 standards, covering the full scope of EV supply equipment safety requirements. The unit also incorporates a built-in temperature monitoring system that guards against overheating during charging sessions. The combination of Swiss engineering and German manufacturing results in a charger that is resistant to drive-overs, impacts, water, and dust — a standard that many competitors simply cannot match.
Versatile Adapter Ecosystem
A major strength of the J+ BOOSTER 2 platform is its broad ecosystem of interchangeable NEMA adapters. From the NEMA 5-15 (standard household outlet) and NEMA 14-50 (common EV-dedicated outlet) to the NEMA TT-30 (RV campground hookups), NEMA 6-50 (workshop and commercial outlets), NEMA L5-30 (marina and twist-lock outlets), and more — a single J+ BOOSTER 2 unit can plug into practically any power source an EV driver is likely to encounter. This makes it an especially practical choice for road-trippers, van-lifers, RV enthusiasts, and anyone who charges at multiple locations throughout the week.
Universal Vehicle Compatibility
The J+ BOOSTER 2 is compatible with all electric vehicles and plug-in hybrids equipped with a J1772 connector, covering the vast majority of EVs on the road today. A J1772-to-NACS adapter bundle is also available, extending compatibility to Tesla vehicles and other models adopting the NACS charging standard. This universal approach means one device serves a multi-EV household or a growing fleet without the need for multiple chargers.
Whether you're a first-time EV owner looking for a reliable home charging solution or a seasoned driver who demands military-grade durability on the road, J+ Booster delivers a compelling combination of performance, portability, and peace of mind.
