How “portable” actually breaks down
Every charger on this page uses a plug, not a hardwired connection — that’s the baseline for even showing up here. But plug-in and pocket-portable aren’t the same claim. The Lectron 40A is built and sized to be genuinely carried: a compact body, a 16-foot cable, and nothing bolted to a wall bracket, so it lives in a bag or a trunk between trips. The Emporia and Grizzl-E are also plug-in, and either will travel if you need it to, but both are heavier units with longer cables designed to live near one outlet most of the time — think “movable if the house changes” rather than “packed for the weekend.” Neither claim is a knock; they’re just different jobs. Our portable versus wall-mounted comparison sets the two side by side.
If the portable is a present, our road-tripper gift list and new-EV-owner gift list cover the same units in gifter terms.
The outlet decides more than the charger does
All three plug into a NEMA 14-50, the common 240V/50A receptacle. Under the National Electrical Code’s continuous-load rule, a 50-amp-rated circuit is limited to 40 amps of continuous draw — the same 80% margin that governs every EV circuit. So even though the Emporia is rated 48A hardwired, on a 14-50 plug it’s capped at 40A right alongside the Lectron and the Grizzl-E. If you want to actually use a charger’s full nameplate rating, that means hardwiring on a bigger circuit — a different install our Level 2 roundup covers. For a plug-in setup, budget for 40A and no higher, and see our charging levels guideif you’re still deciding whether Level 2 is the right tier at all.
What’s actually worth keeping in the trunk
If the plan is genuinely to travel with a charger — a second home, a family member’s driveway, a job site with a 14-50 outlet — weight and cable length matter as much as amps. A shorter cable is lighter to coil and stash, and a unit with no app has one less thing to set up on someone else’s Wi-Fi. That’s the case for the Lectron here: it trades a smart app and a longer warranty for size. If the charger is instead going to live at one house and just happens to unplug, the Emporia’s app-based scheduling or the Grizzl-E’s weatherproof shell earn their extra bulk. Match the pick to which of those two jobs you actually have.
