Both are offering lower-than-average prices, data from Chargenomics shows.
Ionna charges an average of $0.37 per kWh for electricity, according to Paren, giving it the lowest rate among the 17 networks analyzed. Walmart was the fourth cheapest—beat out by Shell Recharge and Rocky Mountain Power—with an average per kWh price of $0.43, again per Paren.
Tesla and Electrify America, for reference, charge an average of $.056 per kWh.
They are the new kids on the block. So to bring attention & business; lower pricing.
I’ve never charged my Tesla anywhere but the 110 V plug in my garage since I drove it home from the dealer in Seattle. I did stop at a Tesla Supercharger station for a free charge on the way home, and it was priced at 39 cents a kwh. I’m paying 8.8 cents a kwh in my garage.
I have yet to use Ionna but I have followed them closely. Rock-solid high powered chargers, support plug and charge for multiple makes, accept payment through multiple systems, as well as credit card readers. Many sites have covered parking. They are doing this right.
Wal-Mart, I believe, were not going to originally support credit card readers but were publicly shamed into it. Use the Wal-Mart app for a discount, or just swipe your card. Unlikely to support plug-and-charge, but a card swipe is no big deal. They are also using very solid, high powered chargers.
