Splitvolt vs NeoCharge

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The verdict, up front. If you have a 30-amp dryer outlet -- which is almost everyone asking this question -- the two brands charge at the same 24 amps and the choice comes down to availability and the socket you need: Splitvolt, in the 14-30 to 14-50 version, is the one we would buy, because it is on Amazon and its EV socket matches the NEMA 14-50 plug most portable chargers ship with. If your laundry or garage outlet is a 14-50, 10-50 or 6-50 on a 50-amp circuit, buy NeoCharge instead: its versions for those outlets are rated 40 amps, and that is a real difference you will feel every night. Either way, a dedicated circuit beats both if your panel can take one.

Side by side

Speed: the circuit decides, not the brand

This is the part most comparisons get wrong by implying one splitter is faster. A splitter cannot create capacity. A dryer circuit is 30 amps, a continuous load may use 80% of its circuit, and 80% of 30 is 24. Both brands land on 24 amps for the same reason, and both enforce it with an internal breaker rather than trusting you to.

Read the left column against your own driving before you worry about the right one. The average US driver covers well under 40 miles a day, and 160 miles overnight covers that several times over. The 40-amp column matters for a truck, a long commute, or a two-EV household -- and in those cases a dedicated circuit is usually the better answer than a bigger splitter.

The outlet-matching trap, which is the real decision

Three plugs have to agree: the one on your wall, the socket the splitter hands you, and the one on your charger. Get any pair wrong and the box goes back. Splitvolt publishes all three for each model, so this is checkable before you buy:

Certification: different marks, same standing

NeoCharge says UL listed. Splitvolt says cETLus listed by Intertek, file 5021938, conforming to UL 60730-1 and certified to CSA E60730-1. Those are different testing laboratories, not different levels of safety: both UL and Intertek are nationally recognized testing laboratories, and a cETLus mark to a UL standard means the product was tested against that same standard. Splitvolt publishing the file number is a point in its favor, because a file number is checkable and a logo is not. How to check a certification covers doing that.

What matters far more than which mark: it must have one. Unlisted Y-splitters and dual-socket adapter cords for 240-volt circuits are sold everywhere and are a genuinely bad idea -- they let both loads draw at once with nothing to stop them. Never a plain splitter explains why the switching is the whole product.

Where you can actually buy each

This is a practical difference worth stating plainly. All three Splitvolt models are listed on Amazon and were verified in stock on the day this page was written. NeoCharge is not: a search of Amazon's catalog for the brand and model returns no NeoCharge-branded listing at all -- what comes back is Splitvolt, VEVOR, and a row of unbranded automatic switches. NeoCharge is sold direct by the maker, which is fine, but it means the two are not equally easy to buy and we earn nothing if you choose it. We would still tell you to choose it on a 50-amp outlet.

Who should buy which

What neither of them fixes

• They take turns. The dryer and the car cannot draw at once -- that is the point of the switching. If someone does laundry at 11 pm, charging pauses.
• Your charger must cooperate. It has to be settable to 24 A or less. Many are; some cheap ones are not. How many amps do you need covers reading your charger's adjustable range.
• Indoor only. Splitvolt publishes indoor use only, and NeoCharge is an indoor plug-in device. A laundry room is fine; an exterior wall is not.
• They do not add capacity to a tired panel. If your service is already near its limit, a splitter avoids a new circuit but does not change the load calculation. Panel load calculation.
• The warranty is short. Splitvolt publishes one year. A charger usually carries three. Factor that in, because this device sits between your dryer circuit and a car.

And the honest alternative we keep coming back to: if your panel has room, a dedicated 14-50 circuit costs money once and then charges at 40 amps forever with no device in the middle and no laundry conflicts. What a NEMA 14-50 install costs has the published numbers. A splitter is the right answer when that circuit is genuinely not available -- a full panel, a rental, or a quote that came back at four figures.

Both brands, and the model that fits your wall

The three Splitvolt models in the order most readers need them, and NeoCharge for a 50-amp outlet. Prices are live from Amazon and carry the date they were read; NeoCharge has no Amazon listing, so its row links to a model search.

1. A 14-30 dryer outlet and a charger with a 14-50 plug

Splitvolt Splitter Switch (NEMA 14-30 to 14-50)

Splitvolt · NEMA 14-50 · 24 A / 5.8 kW

The one most people need: it plugs into a four-prong 14-30 dryer outlet and gives the charger a NEMA 14-50 socket, which is the plug nearly every plug-in EV charger ships with. Still 24 A, because the dryer circuit is still 30 A.

What is good

• +A 14-50 EV socket, which is the plug most plug-in chargers already have
• +Fits the four-prong 14-30 dryer outlet modern circuits use
• +Automated switching, full-color metering display and an easy-reset 24 A breaker
• +cETLus listed with the Intertek file number published
• +No new circuit, so no panel upgrade

What is not

• −A 14-50 socket that still only delivers 24 A -- the outlet looks faster than it is
• −The dryer and the charger take turns; they cannot run together
• −Indoor use only
• −1-year warranty

3. Older 10-30 dryer outlets

Splitvolt Splitter Switch (NEMA 10-30)

Splitvolt · NEMA 10-30 · 24 A / 5.8 kW

Shares an older three-prong 30-amp dryer outlet between the dryer and the charger, with an internal breaker holding charging to 24 A. This model's EV socket is also a NEMA 10-30; Splitvolt sells a separate version with a 14-50 EV outlet. cETLus listed with a published file number.

What is good

• +cETLus listed, with the Intertek file number published
• +Integrated 24 A breaker keeps charging inside the limit of a 30 A circuit
• +Switches between dryer and EV automatically -- no plug swapping
• +Full-color display reports real-time kWh, amps and volts
• +Plugs in -- the splitter itself needs no electrician installation

What is not

• −Your charger must be able to limit itself to 24 A
• −The EV socket is a NEMA 10-30, so a charger with a 14-50 plug needs a different model
• −24 A is about 20 miles of range per hour -- slow for a big battery
• −Indoor use only, and a 1-year warranty against the 3 years most chargers carry
