ShockFlo EV Charger Featueres: 

Effortless EV Charging and Beyond

The ShockFlo EV Charger boasts a unique and convenient feature that sets it apart from traditional chargers—it doubles as a powerful tire inflator. This all-in-one functionality aims to simplify the lives of EV owners who value versatility and practicality.

Fast and Efficient Tire Inflation

The standout feature of the ShockFlo EV Charger is its tire inflation capability. With its ultra-fast inflation rate, it can inflate a standard 195/60/R16 car tire from 20 to 35 PSI in just one minute, while taking a mere 4.5 minutes to go from 0 to 35 PSI. The maximum range of 150 PSI and support for four pressure units (PSI, BAR, KPA, KG/CM²) make it versatile for various inflation needs.

Dual Power Supply Options

The device offers two power supply options—a 7800mAh Li-ion battery and 12V DC. The built-in battery enables cordless operation, allowing users to use it anywhere without being tied to a power source. For extended use or emergencies, the 12V DC option provides a continuous power supply. However, some users have noted that the power cord’s length may pose an inconvenience, particularly for larger vehicles that require an extension cord.

User-Friendly Interface and Smart Preset Modes

The ShockFlo EV Charger features a user-friendly smart HD touchscreen with a large LED display. It shows both real-time pressure values and preset values, simplifying tire inflation by providing essential information at a glance. The five intelligent preset modes and automatic shutoff feature further enhance convenience, ensuring accurate inflation without the risk of overinflation.

Compact Design and Bright Emergency Light

With its compact dimensions of 7.4 x 2.9 x 4.5 inches, the ShockFlo EV Charger is designed for easy storage, making it ideal for on-the-go usage. Additionally, the built-in bright emergency light with multiple modes—emergency lighting, SOS blinking, and warning lights—provides added safety during unexpected situations.

Readable Display in Various Conditions

While the LED display excels in clarity, some users have reported difficulty reading it in direct sunlight. As a crucial component for precise tire inflation, this concern may be a drawback for those who often use the charger outdoors in bright conditions.

Pros and Cons

The ShockFlo EV Charger has received widespread praise for its ultra-fast tire inflation, dual power supply options, and smart preset modes. The convenience it offers makes it an ideal solution for electric vehicle owners, allowing them to take charge of their tire inflation needs with ease. Additionally, the bright emergency light enhances safety and peace of mind.

However, a few drawbacks have been noted by users. Some customers found the power cord to be too short for trucks and SUVs, necessitating an extension cord for comfortable usage. Additionally, the air hose’s short length made it less suitable for vehicles with large wheels, requiring users to hold or balance the pump during inflation. Furthermore, the display’s readability under full sunlight was cited as a concern.


The ShockFlo EV Charger offers a unique blend of EV charging and tire inflation capabilities, making it an attractive option for electric vehicle owners seeking convenience and versatility. Its fast inflation rate and dual power supply options provide practical solutions for various situations. However, the device’s short power cord and air hose, along with display readability issues under bright sunlight, are aspects worth considering before making a purchase.

As objective car electronics bloggers, we recognize the ShockFlo EV Charger’s potential as a valuable addition to any EV owner’s toolkit. It delivers on its promise of efficient tire inflation and easy EV charging, providing a compelling option for those seeking a comprehensive charging solution on the go.
