FAQ – Industry / General Information
How does home charging work?

Your home charging station is typically mounted on an indoor or outdoor wall and connected to your home’s electrical system. You connect the plug when you park your car and disconnect it when you’re ready to drive.

What are the advantages to home charging? It’s charging on your schedule. You can charge while you sleep or do other activities so your car is ready when you are.

FAQ – EV Chargers

I received a basic L1 charger when I bought my vehicle. Why should I get a Splitvolt Level 2 portable EV Home Charger?

Currently, over 80% of vehicle charging takes place at home because it is the most convenient and cost-effective way to charge your vehicle.   Today’s newer EVs have much larger capacities and single charge ranges from 300-500 miles.  Common 120V (L1) trickle chargers are just too slow and have a maximum charging rate of 3 miles per hour–meaning it could take it over 100 hours for a full charge!   The Splitvolt 240V L2 Fast Mobile Home Charger provides up to 7x – 12x times FASTER CHARGING at rates between 21-37 miles per hour and is small/portable for travel convenience.

Why sell both a Splitvolt Splitter Switch and Splitvolt electric vehicle charger?

These two products serve related, yet very different purposes and are complementary.  A Splitvolt Splitter Switch can be used to efficiently and cost-effectively provide power to the Splitvolt EV chargers, but the EV chargers work equally well without the Splitter Switch when connected to dedicated 240V charging circuits.  

Will the Splitvolt portable EV chargers connect to my electric vehicle?  

Yes, they connect to all common US electric vehicles using a standard J1772 interface. For Teslas, the charger connects using the J1772 adapter that came with the vehicle. 

Do I need an Electrician to install Splitvolt portable EV chargers?

Nope!  This product is completely plug & play.  Just plug it in to a standard household 220-240V circuit with NEMA 10-30, 14-30 or 14-50 sockets and that’s it!  

Can I mount it to a wall?

There is a slot in the back of the EV charger control box so it may be easily hung using a standard screw and then may be removed and replaced by hand without any tools.

Do Splitvolt EV chargers include a warranty?

Yes, we offer a standard one-year warranty on all of our products.

What is the fastest safe charging rate on a standard 30amp or 50amp household 220-240V circuit according to the National Electrical Code (NEC)?

The NEC states that the maximum continuous safe charging rate for EV chargers is 80% of their stated load.  That means a 30amp circuit may safely charge at up to 24amps, and a 50amp circuit may charge at up to 40amps.  Charging rates beyond this on these circuits are not safe and do not meet NEC standards.

Does Splitvolt sell other products besides the Splitvolt EV chargers?

Yes!  Splitvolt also sells a new category of product called the Splitvolt Splitter Switch.  This device allows users to share the power from an existing 30amp dryer socket with their EV charger, without the high cost and complexity of having an electrician install an additional dedicated circuit.  

How much does it cost to have an electrician install a dedicated EV charging power circuit in my house?

This depends upon a number of factors including how far away from the subpanel, as well as the particular region you live in.  For example, in the San Francisco Bay Area, even a simple dedicated circuit installation can cost $600-800.  Also, if your home is older and does not have sufficient additional amperage available, you may need the local utility to run more power which can cost thousands of dollars more.

What are the dimensions of the box?

The unit weight is 7.7 lbs., the control box dimensions are 9.5 IN x 4 IN, and the cable length is 16.4 FT.

What do the color LEDs show?

The Splitvolt portable EV charger has LEDs on the control box to indicate EV charging status.  These LEDs show power to the device, charging status, as well as multiple Fault indicators which have a flashing patter to indicate the fault status. The pattern and resulting status is indicated on the table printed on the back of the control box for convenient reference.

What if I don’t have a dryer or other 220-240V circuit in my garage or near my vehicle?  

In this case, you may be able to use 240V extension cables to reach your vehicle charger.  They are for sale by Splitvolt and other third-parties.

FAQ – Splitvolt EV Splitter Switches
What is a Splitvolt EV Splitter Switch?

A Splitvolt EV Splitter Switch is a brand new category of product that allows you to share your existing, standard 240v, 30amp dryer socket with your EV charger. It intelligently and safely switches full power between your dryer and EV charger on demand—with no user intervention required.

It is a small shoebox sized device that you plug into your 240v wall socket, and then plug both your dryer and EV charger into it. The device will automatically sense when the dryer is in use, and provide full power to it until the cycle completes and then automatically switches power over to your EV charger so your vehicle will charge at maximum safe rate at all times other than when the dryer is running.

No electrician or complex installation required—just plug it in and you’re off-and-running at maximum safe charging rate for your standard circuit.

FAQ – “Dumb” Splitter Connectors
Why is it unsafe to use a basic splitter cable from a home electrical store to connect both my dryer and EV charger to the same 240v socket?

Normal splitter cables or connectors are not safe for shared use by EV chargers and dryers on the same 240v socket. This happens because both connections are “live” at the same time, and will overload the circuit causing a dangerous situation in which household wiring may potentially overheat and cause a fire hazard. This will also lead to frequent tripping of the household circuit breaker causing loss of household power and requiring manual reset.

FAQ – Splitvolt Extension Cables & Adapters
What are Splitvolt extension cables and adapters?

Splitvolt extension cables and adapters are convenience products that make it easier for your EV charger or Splitvolt Splitter Switch to reach your vehicle. There are multiple lengths as well as various socket and plug interface combinations. Primary interfaces are NEMA 10-30, NEMA 14-30 and NEMA 14-50.

In the event of a discrepancy between this FAQ and Amazon’s return policy, Amazon’s return policy shall govern.
FAQ – Technology & Standards Reference Information
What are some of the related technology and standards that relate to Splitvolt products?

The National Electrical Code (NEC) is a home power safety standards organization that defines the safety codes used in the United States. Each state will generally adopt those NEC codes, or similar variations, such as those adopted in the California Electrical Code (CEC) standard. These include home wiring gauge (thickness) for various current loads and other requirements relating to home electrical safety. The NEC states that for standard household 240v 30amp AC power circuits, the maximum safe EV charging rate is 24amps. EV chargers connecting to these circuits should be set for a maximum of 24amp charging rates to avoid risk of fire or home circuit breaker tripping. You may need to manually set the charging limit on your vehicle or EV charger if it tries to charge at higher than 24amps. The NEC maximum safe charging rate for 50amp circuits is 40amps. Charging should never exceed 40amps on such circuits.

NEMA is a standards body in the United States that defines the standard connector types for household and business plugs and sockets. The most common existing standard 240v 30amp dryer socket type in the U.S. is the NEMA 10-30. A less common but newer standard 240v 30amp dryer socket type is NEMA 14-30. Both of these sockets are used on 30amp circuits, and may be used to charge an EV up to a maximum of 24amps. Special 240v 50amp AC circuits are sometimes installed in homes for applications requiring more power. Such 50amp circuits most commonly use NEMA 14-50 sockets and may safely charge EVs up to 40amps.
