Zendure mentions support for Amazon Alexa and Google Home, enabling you to issue voice commands to your Superbase V6400. I only got the option to link Alexa in the Zendure app, and I needed some help to set up the Zendure skill, but I could not get Alexa to recognize any voice commands. I’m not sure how useful voice commands would be here anyway, and you can control the Superbase remotely using the app on your phone.
The Superbase V6400 can also function as a seamless UPS, automatically switching to battery during any outage. Zendure claims the US model of SuperBase V can switch to battery power with 0 milliseconds of downtime (13 ms for other connections and models), and that seems to be accurate. But you will likely want a transfer switch installed by an electrician if you want power throughout your house. Zendure offers a Smart Home Panel with EV Outlets ($1,200) that combines a transfer switch and dock for the Superbase V and has two EV charging ports.
As a modular system, you can add up to four B6400 satellite batteries (6.4 kWh each) to a Superbase V6400. The design includes removable rubber strips on top to stack extra batteries securely. You can also link two Superbase V6400s together, and with four batteries apiece, that would allow you to store up to 64 kWh. That’s enough to power your entire home for a few days or charge your EV. But even with discounts, a system like that will cost you $41,800 at the time of writing.
For comparison, a Tesla Powerwall 2 home battery has a 13.5-kWh capacity and costs $12,850, but you can only get them with a solar panel installation (unless you buy used). You would need five to get a similar storage capacity (67.5 kWh), which comes to $46,750 with current pricing and discounts.
For off-grid RV camping, the Superbase V6400, paired with a decent solar panel array, could work well if you have the space. Just make sure you get help loading it. After a couple of cycles using it around my home, the Superbase V6400 performs as I’d hope. But longevity is crucial for energy storage, and only time can tell how well it performs over months and years. The standard warranty is three years, and you can extend that by a further two years by registering in the Zendure app.
Zendure also offers a Superbase V4600 with a 4.6-kWh capacity for $3,300. But it contains LiFePO 4, rather than semi-solid-state, batteries, and we have not tested it. If you want something more affordable and portable, try Zendure’s smaller power stations. I tested the SuperBase Pro 2000 ($1,600), which uses LiNiMnCoO2 batteries with a 2-kWh capacity. It’s much more manageable, with a telescopic handle and plenty of outlets and ports for camping trips or emergencies. Sadly, you can’t mix and match different battery types; the V6400 system only pairs with B6400 batteries.
We are seeing a flood of portable power stations hitting the market, and we plan to test several competitors in the coming months. For now, Zendure’s slick modular system has set a high bar. For folks seeking high-capacity, scalable energy storage, the Superbase V6400 will be hard to overlook.
