WOLFBOX Level 2 EV Charger Review: 50 Amp Hardwired with Smart App and RFID Control

Introduction

If you’re shopping for a Level 2 home EV charger, you’ve likely noticed that the market splits into two camps: plug-in units that let you move the charger between locations, and hardwired units that offer a cleaner, more permanent installation. WOLFBOX offers both options within its current lineup, and both share a similar feature set—smart app control, RFID card security, and a 25-foot cable—but they differ in amperage and installation method.

In this buyer’s guide, we’ll compare the WOLFBOX Level 2 EV Charger 50 Amp (with NEMA 14-50 plug) against the WOLFBOX Level 2 EV Charger 48 Amp (hardwired with smart display) . Both are solid choices for home charging, but one may suit your setup better depending on your electrical panel capacity, whether you rent or own, and how much you value a built-in display.

At a Glance

Where the 50 Amp (Plug-In) Model Wins

Flexibility for Renters or Future Moves

The 50 Amp model uses a NEMA 14-50 plug, which is the same outlet found on many RV parks and newer home garages. If you rent or plan to move within a few years, a plug-in charger is far easier to take with you than a hardwired unit. You simply unplug it, pack the 25-foot cable, and reinstall at your next location—no electrician required for the move itself.

Higher Amperage Capacity

This unit is rated at 50 amps, which means it can deliver more current than the 48-amp model if your electrical panel and breaker support it. For drivers with larger battery packs or those who want the fastest possible home charging speed, the extra headroom can make a difference. Note that actual charging speed also depends on your vehicle’s onboard charger, but the 50-amp capacity gives you the maximum possible throughput for a Level 2 setup.

Simpler Installation for DIY Owners

If you already have a NEMA 14-50 outlet installed in your garage, installation is as simple as plugging in the unit and mounting the bracket. No need to open your breaker panel or run new wiring. This also makes it a good option for homeowners who are comfortable with basic electrical work but want to avoid a full hardwired installation.

Where the 48 Amp (Hardwired) Model Wins

Built-In Smart Display

The 48-amp model includes a smart display on the unit itself, which shows charging status, power flow, and other information at a glance. While the 50-amp model relies entirely on the app for detailed feedback, the hardwired version lets you check charging progress without pulling out your phone. This is particularly handy if you park in a garage where the charger is visible from the driver’s seat.

Cleaner, Permanent Installation

Hardwiring the charger means no visible plug, no risk of the unit being accidentally unplugged, and a flush mount against the wall. It also eliminates the small but real risk of a plug connection overheating over years of use—hardwired connections are generally considered more robust for continuous high-current loads. If you own your home and plan to stay put, the hardwired model offers a more professional-looking, permanent solution.

More Reviews and Established Track Record

With 137 reviews and a 4.6 rating, the 48-amp model has a larger sample size of user feedback compared to the 50-amp unit’s 44 reviews. While both are highly rated, the hardwired version has been on the market longer or sold in greater volume, giving you more data points to gauge reliability and customer satisfaction.

Slightly Lower Price

At ~$419.98, the 48-amp model is about $10 less than the 50-amp unit. The difference is small, but if you’re on a tight budget and don’t need the plug-in flexibility, the hardwired model gives you a smart display for a lower cost.

Verdict by Use Case

Choose the 50 Amp Plug-In Model If…

• You rent or may move within a few years. The NEMA 14-50 plug makes relocation simple.
• You already have a NEMA 14-50 outlet installed. No electrician visit needed.
• You want the highest possible amperage capacity for future-proofing or faster charging on compatible vehicles.
• You prefer a DIY-friendly installation that doesn’t require opening your breaker panel.

Choose the 48 Amp Hardwired Model If…

• You own your home and want a permanent, clean installation.
• You want a built-in display for at-a-glance charging status without using the app.
• You prefer a hardwired connection for long-term reliability and safety.
• You value a larger review base (137 reviews vs. 44) to help inform your purchase.

For Most Homeowners

If you own your home and have access to an electrician for the initial hardwired installation, the 48-amp model offers a slightly lower price, a smart display, and a proven track record with more reviews. If you rent or want the ability to take your charger with you, the 50-amp plug-in model is the more practical choice.

Both chargers deliver Level 2 charging with smart app control, RFID card security, and a 25-foot cable—so your decision comes down to installation preference and whether the display matters to you.
