Lectron V-BOX Pro Review: 48 A with Wi-Fi and Bluetooth

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.

Lectron is best known on this site for adapters and portables. The V-BOX Pro is its wall unit: a J1772 charger that can go on a 14-50 now and be hardwired later. We have not tested one; figures come from Lectron's product page, linked at the foot of this page.

Plug-in or hardwired

The two ways to install it

On a NEMA 14-50 (50 A circuit): 40 A x 240 V = 9.6 kW, about 34 miles per hour

Hardwired on a 60 A circuit: 48 A x 240 V = 11.52 kW, about 40 miles per hour

Circuit for 48 A: 48 x 1.25 = 60 A

The same unit covering both is useful if you are renting now or unsure of your panel: plug in today, hardwire later if the load calculation allows. Hardwired vs plug-in.

The cable is the catch

At 16 ft, the V-BOX Pro's cable is the shortest of the wall units on this site; most publish 24 or 25 ft. Measure from the mounting spot to your charge port first, and never add a household extension cord. Cable length guide.

Who should skip it

Your charge port is more than about 16 ft from the wall.
You want no app at all. Chargers without an app.
You want the toughest case. The Grizzl-E Classic's cast-aluminum NEMA 4 / IP67 box is the comparison. V-BOX Pro vs Grizzl-E.

FAQ

Questions people actually ask

Is the Lectron V-BOX Pro any good?

On paper it offers a lot: 48 A hardwired or 40 A plug-in, app control over Wi-Fi or Bluetooth, and an IP65 enclosure. The 16 ft cable is its main limitation.

How long is the Lectron V-BOX Pro's cable?

16 ft, per Lectron.

Can the V-BOX Pro charge a Tesla?

It has a J1772 connector, so a Tesla charges through a J1772-to-NACS adapter, as Lectron notes.
