The Energbison Level 1 & 2 J1772 EV Charger is a highly adaptable, budget-friendly power solution tailored for drivers who want flexibility without investing in an expensive, permanent home installation. 

Operating as both a standard Level 1 and a faster Level 2 charger, this portable unit serves as an excellent emergency backup or a straightforward daily charging option that you can simply pack away for road trips. 

Out of the box, the unit features a native NEMA 6-20 plug for 240V Level 2 charging, but it also includes a convenient NEMA 5-15 adapter. This configuration means you can plug it straight into a standard domestic three-prong wall outlet if a heavy-duty circuit is unavailable. 

It carries an IP66 weatherproof rating and incorporates ten layers of safety protection, making it highly resilient against dust and harsh outdoor elements. A clear digital display on the front face provides real-time diagnostics, while physical controls allow users to adjust amperage settings to optimise energy consumption for various electric vehicle (EV) models.

Reasons to buy

Dual-voltage flexibility: The combination of a NEMA 6-20 plug and an included NEMA 5-15 adapter allows you to charge from standard or high-voltage sockets seamlessly. 

Generous cable length: The 25-foot flame-retardant cable offers plenty of reach, making it easy to park your vehicle away from the immediate vicinity of the electrical outlet. 

Onboard information screen: The built-in digital display clearly provides vital operational details, including charging time, current amperage, and delivered power. 

Adjustable current settings: Offers an adjustable current feature that allows users to customize charging speeds, which helps optimise energy consumption and enhance battery longevity. 

Robust build quality: An IP66 weather resistance rating alongside a drop-resistant plug ensures the unit handles outdoor charging safely under extreme conditions. 

Reasons to Avoid 

Limited charging speed: Maxing out at 16 Amps means it is intended for steady overnight top-ups or backup usage, rather than high-speed rapid charging. 

Not for high-capacity rapid needs: May not meet the strict requirements of EV owners who need super-fast home charging solutions for high-capacity batteries. 

No smart application integration: Lacks built-in WiFi or Bluetooth connectivity, meaning management is fully handled directly on the unit rather than a smartphone application.
