Can I get by with a Portable EV Charger or do I need an EV Charging Station?

Occasional Use Charger, Trickle Charger, Emergency Charger or Portable EV charger, these names all refer to the same thing, a small portable charging cable for your electric vehicle, which can be plugged into any domestic 10amp/240 volt household PowerPoint.


Given its low charging ability, a portable EV charger is classed as Level 1 Electric Vehicle Supply Equipment (EVSE) – a generic term for any type EV charging equipment.


As the name suggests this charger is a portable solution to make sure you are never caught short of a charge, it is literally impossible to not be able to plug into a 10amp socket somewhere. The downside of this portability is the charging speed is not particularly fast.


This is often a standard accessory on most electric vehicles such as the BMW i3 and BMW i8 and Nissan Leaf, taking the prized position in the trunk or frunk (front trunk) of most EVs.

The Anatomy of a Portable EV Charger

On one end lives a standard mains power cord, which has a three pin plug which will plug into any household wall socket. On the other is a thicker cable attached to either a J1772 (Type 1) or Mennekes (Type 2) Plug that connects into your EV. In between the two cables is the charging box itself, which contains a comprehensive protection system and short circuit protection designed to allow for safe portable EV charging. The overall length of the Portable EV Charger is 5.5m which is enough in most cases to get you a charge almost anywhere.


Can you use an extension cable with your Portable EV Charger?

No, this is not recommended given the cord could be damaged, may not be weatherproof and generally may not be able to withstand the close to the maximal draw of the Portable EV charger over several hours without compromising safety.


What are the built-in safety features incorporated into the EVSE Portable EV Charger?

  • Auto charge recovery
  • Overcurrent protection
  • RCD inbuilt
  • Modified three pin plug to ensure only the portable is charging off the domestic socket to avoid overload
  • Down-regulated to draw 8AMP/240V to avoid overload.

*Please note these advanced safety features are not found in portable EV chargers on the market.


So which portable EV Charger do I need for my electric vehicle?

Type 1 (J1772) – BMW i3, BMW 330e, BMW X5 xDrive40e, Holden Volt, Nissan Leaf, Mitsubishi Outlander PHEV, Toyota Prius Plug-in, Volvo XC90 T8, Audi A3 e-tron, Mercedes Benz C-Class 350 e Sedan, E 350 e, GLE 500 e, S500 e.

Type 2 (Mennekes) – Tesla Model S, Tesla Model 3, Tesla Model X, Renault Zoe ZE, Hyundai Ioniq (Pending)


Can you survive with only a Portable EV Charger or do you need a Hardwired EV Charging station for your home?

For some vehicles, it could be possible such as plug-in hybrids (PHEV) with a low EV range, but generally speaking, we would advise most drivers to install a hardwired EV charger such as the Keba P30 or EO Charger into their home garage or parking space. Not only is this more convenient, between 3-10 times faster, it is also a far safer option.  If you do persist with a portable charger as your primary EV charger, then we always recommend you have an electrician check the outlet and circuit to ensure its safe operation and follow the manufactures instructions.


The Bottom Line

A portable EVSE is an essential item for all EV drivers to have and keep in their boot of their EV to ensure they are never caught short of a Charge.
