ShockFlo EV Charger Review- Best Portable EV Charger?

Upon acquiring my first EV I experienced pure joy because it meant no more gas payments and minimal maintenance costs and the added benefit of peaceful driving. Excitement faded away as I faced charging requirements each day. Users faced several barriers when using public charging facilities because these stations were distant, slow or excessively pricey. 

The ShockFlo G1 Level 2 EV Charger became the solution I found after my search. The unit delivered speed alongside smart safety functions in a system that functioned automatically with no need for electrician involvement. 

Shockflo ev charger holds all necessary information one needs prior to making a purchase of the ShockFlo Level 2 EV Charger.

My Experience with the ShockFlo G1

Easy Setup in My Garage

I already had a NEMA 14-50 outlet in my garage—used occasionally for a welder—so setup took all of five minutes. I mounted the included wall bracket, plugged it in, and started charging. No configurations. No headaches. This truly is plug-and-play.

I’ve also tried it in my driveway by running the cable under the garage door—no issues thanks to the 20-foot cable, which had more than enough reach.

Daily Charging Performance

Let’s talk speed. At the full 32A output, I was getting around 24 miles of range per hour (tested on a Chevy Bolt and a Tesla Model Y with the J1772 adapter). That meant a full overnight top-up even if I got home with near-zero battery.

What impressed me most was consistency. Even when ambient temps rose during a heatwave, the unit throttled slightly for battery safety but never failed or overheated. 

The auto shutoff when fully charged also gave me peace of mind when charging overnight.

Portability on the Go

We took the ShockFlo G1 on a four-day trip to visit family across two states. With its 7-pound weight and included carry bag, tossing it in the trunk was easy. 

I used it at an Airbnb and a friend’s house (both had 14-50 outlets). It worked flawlessly, saving me time and cost vs. public DC fast chargers.

Standout Features That Solved My Charging Problems

Adjustable Current Settings (10A–32A)

Sometimes you need full power; other times, you’re limited by the outlet. With five current levels to choose from, I could drop to 10A at a campsite or crank it up to 32A at home. This helped avoid tripping breakers and ensured safe operation no matter where I was.

Delay Start Timer (1–12 Hours)

I use a time-of-use electricity plan where rates drop after 11 PM. With the delay timer, I simply set it to begin charging 3 hours after plugging in. It kicks in automatically and saves me real money each month.

Smart Safety & Certifications

ETL and FCC certifications were reassuring, but it’s the built-in protection system that impressed me: surge protection, leakage protection, temperature control, and auto shutoff. Everything’s clearly displayed on the LED screen, which is bright and readable—even in my dim garage.
