The cord that comes with Bolts is either 120V only, or with EUV (or optional on EV) it is dual voltage. The dual voltage cord is 32A on 240V or 8/12A on 120V and not configurable on 240V, the 120V (8A or 12A) setting is in the Energy screens in the Infotainment system. However, both the 120V, and the dual voltage cord (with the 120V cord attached) can supply 240V@12A with adapters. Some find this "hack" to be too risky, so follow your own risk tolerance if considering going that route.
If you don't want to take the risk, or feel 16A would better suit your needs, the chart at the beginning of
this thread will give you an idea of how much range you can expect to recover at various power levels. For instance, 16A (highest level you should attempt to use on 20A circuits) will give you 240*16 = 3.84kW, so about 12-16 miles of range per hour on the plug. The 120V cord (or dual cord with 120V plug) and 240V adapters will yield 2.88kW or 9-12 miles per hour. From these numbers, you can determine how well each option might meet your daily needs. If it comes up a little short, you might be ok making up for it over weekends, or occasionally using public chargers.
I assume you are aware, but worth mentioning, the cord does not lock to the port so a small luggage sized lock inserted in the release lever of the J1772 plug might be wise if you are concerned about cord theft.
Here is a lock sold by a maker of Tesla adapters (see next paragraph) that seems to work really well, I use it on a Tesla Tap adapter, but it should work on virtually any J1772 plug that has a hole for locking the handle.
If you choose to go with a 16A or adjustable cord, there are a few options described in
this section. One reasonably priced option is the Tesla mobile cord (aka UMC), but it requires an adapter to work with the J1772 outlet in the car. The adapter is good to have for travels as some public chargers and many hotels have Tesla Destination (Level 2) chargers. With the Tesla UMC, the cord and adapter will not lock to each other. If you are handy, someone recently posted a link to a video on a guy who replaced the Tesla plug with a J1772 plug on a Tesla UMC, but that was a bit involved. The great thing with the Tesla UMC is that you can buy adapters for nearly any type of outlet and the unit will automatically set the max output to the car based the adapter attached to the unit. If you go this route, it is important to buy an adapter that is rated for 50A or more because the 2022+ Bolts can charge at up to 48A. Many Tesla destination chargers are higher powered, so you don't want to fry the adapter. Here is the
Tesla Tap site, Lectron also makes adapters and sells them on Amazon.
Beware of cheap Chinese knock off brands, many reports of them melting to the charge port. Search Mustart on this site for examples.
