NeoCharge Smart Splitter (NEMA 14-50)
A UL-listed smart splitter that shares one existing 240 V outlet between two loads (two EV chargers on the 14-50 version), switching automatically so the circuit is never overloaded.

What's good
- Shares an existing 14-50 outlet on a 50 A breaker between two EVs with zero panel work
- UL listing: the spec that separates it from the no-name splitter listings
- Automatic switching means nobody re-plugs anything, ever
What's not
- Indoor rated only
- The outlet must be on a 50 A breaker for 40 A charging: a 40 A range circuit is not enough
- For EV use, only the 4-wire 14-30 dryer version: a 3-wire 10-30 outlet has no equipment ground, and an EV charger may not use the neutral as one
Our verdict
For renters and full-panel houses, this is the lowest-effort legitimate route to more Level 2 charging: no electrician, no load calculation, no landlord negotiation, the outlet you already have, shared safely. The UL listing is what makes it recommendable where the knockoffs aren't.
