Portable EV Charger Buying Guide

Key Factors to Consider

1. Charging Speed (Amperage)

Higher amps = faster charging. But you need the right outlet and circuit:

  • 16A: Works on 20A circuits (common workshop outlets). ~12 miles/hour.
  • 32A: Requires 40A circuit. ~25 miles/hour.
  • 40A: Requires 50A circuit (NEMA 14-50). ~30 miles/hour.
  • 48A: Requires 60A circuit. ~37 miles/hour.
2. Plug Type

Most portable chargers use NEMA 14-50 (the same as electric ranges). If you have a different outlet, you'll need an adapter:

  • NEMA 14-50: Most common for EV charging. 240V, 50A circuit.
  • NEMA 6-50: Common for welders. 240V, 50A, no neutral.
  • NEMA 14-30: Dryer outlets. 240V, 30A circuit.
  • NEMA 6-20: Workshop outlets. 240V, 20A circuit.
3. Cable Length

Longer is better for flexibility. Most chargers offer 20-25 feet. Consider where you'll park relative to your outlet.

4. Weather Rating

If you'll charge outdoors, look for IP65 or higher water resistance. The Grizzl-E is best for extreme temperatures.

5. Smart Features

Most portable chargers skip WiFi to reduce cost and complexity. If you need scheduling or energy tracking, consider the Emporia or a wall-mounted smart charger instead.

Portable vs. Wall-Mounted Chargers

Should you get a portable charger or a wall-mounted unit? Here's when each makes sense:

Choose Portable If:

Choose Wall-Mounted If:

Pro Tip: Many EV owners buy a portable charger first, then add a wall-mounted unit later. The portable becomes a travel/backup charger. This approach lets you start charging immediately while planning your permanent installation.

Installation Requirements

Using a portable EV charger is simple—if you have the right outlet. Here's what you need:

For 40-48A Portable Chargers

You need a NEMA 14-50 outlet on a 50A or 60A circuit. If you don't have one, expect to pay $300-700 for professional installation (outlet + wiring + breaker). See our NEMA 14-50 installation guide for DIY details.

For 16-32A Portable Chargers

Lower-amperage chargers can use more common outlets. A NEMA 6-20 (240V, 20A) is found in many garages and workshops. If you have an electric dryer outlet (NEMA 14-30), you can use that with an adapter.

Safety Note: Never use a standard extension cord with an EV charger. If you need more reach, use a properly rated EV charging extension cord or install the outlet closer to your parking spot.

Frequently Asked Questions

Can I use a portable EV charger with any electric vehicle?
Yes, as long as the charger has a J1772 connector (standard in North America). Tesla vehicles need a J1772 to Tesla adapter, which is inexpensive and widely available. Newer Teslas with NACS ports need a NACS adapter for J1772 chargers.
How long does it take to charge with a portable charger?
Charging time depends on your charger's amperage and your EV's battery size. A 48A charger adds about 37 miles of range per hour. A typical EV with a 60 kWh battery would go from 20% to 80% in roughly 4-5 hours at 48A, or 6-7 hours at 32A.
Is a portable charger as fast as a wall-mounted charger?
Top portable chargers (48A) match most wall-mounted units. The fastest hardwired chargers offer 60A, which is about 20% faster than 48A portable units. For most drivers who charge overnight, the difference is negligible.
Can I leave a portable charger plugged in outdoors?
If it's rated IP65 or higher, yes. The Grizzl-E and Lectron V-BOX handle outdoor conditions well. However, extreme heat can trigger thermal protection, and the connector should stay dry. A simple cover or garage installation is ideal.
Do I need an electrician to use a portable EV charger?
Not if you already have a compatible outlet. Installing a new outlet (like NEMA 14-50) typically requires an electrician unless you're experienced with electrical work. See our outlet installation guide for details.
