A brand new kind of battery charger that promises to “do all the things you want it to” by replacing old, over-the-air firmware.
The latest in the battery-power battle is the $149 Tesla Powerwall, a small-form-factor USB-C to Lightning-powered charger that’s a little more powerful than your average USB-A charger.
The Powerwall’s USB-I ports are larger than those found on your standard USB-B charger and have a built-in battery.
While the Powerwall isn’t the most powerful device out there, it’s one that could make a significant dent in the industry.
Tesla’s Powerwall is a little smaller than the Lightning, but the difference is that it’s USB 3.0 compatible.
The USB-3 charging port on the PowerWall is the same as on your average Lightning charger.
It’s a small, low-profile, USB-P plug that can charge a variety of devices, including an Apple iPhone 6 Plus or Galaxy Note 5.
The Lightning-to-USB-C cable is made of a high-quality silicone material that’s easier to grip and is a bit thicker than your standard cable.
It plugs into the Powerwalls USB-2 port on both the left and right side, and the PowerWalls USB 3 port is the left side.
Tesla recommends charging at the same speed as its Lightning-equipped competitors (12-17 watts) but it’s also compatible with standard Lightning cables that come with an extension cord.
The battery-powered Powerwall doesn’t come with a power adapter, so if you’re using it as a backup for your smartphone or tablet, you’ll need to buy a separate battery.
The power-hungry Tesla Powerwalled charger will charge an Apple 12.9-inch MacBook Pro, an Apple 13-inch iPad Pro, and an iPad Mini.
The $149 Powerwall also supports a variety a standard USB cables.
The charger’s USB 2.0 ports are a little wider than the standard USB ports, so you can use it with a USB-1 cable.
For most USB-connected devices, the Power Wall charges at 12 watts or more, so the charging rate isn’t particularly impressive.
However, the charger is able to power up to 30% of your iPhone’s battery.
If you’re worried about your iPhone battery getting too low, you can plug the Power Walled charger into the USB-4 port on your iPhone.
The iPhone-powered USB-S adapter can charge the Power and Lightning chargers, and if you use it to charge an iPad Pro or iPhone 6, you could even charge an entire iPad Mini battery with the Power.
The Tesla PowerWalled has a removable battery cover that allows you to remove it if you don’t need to charge it, but we’ll let you know if it does anything to the Power’s charging rate.
The included charger is made out of a low-quality, silicone material, so it’s not going to get very warm.
The charging cable is also made out a different material than what you’d find on the Lightning- or USB-Wired-powered chargers.
While you’ll want to be able to grip the charging cable to keep it from slipping off your fingers, you should be able and expect to get about a full charge.
We’d also recommend charging the Power wall on a regular schedule, as it’ll get more than a full hour of use in under an hour.
While charging is quick, we’d avoid using the Power for extended periods of time.
Battery life varies from device to device, so be sure to read our guide on how to use a smartphone as a battery charger to get the most out of the Power, Powerwall or Tesla Powerchargers.
We tested the Power in a variety.
The 12.7-inch iPhone 6s Plus, a MacBook Pro 11.9″ and an Apple iPad Pro 13″ were all charged with the 12.5-volt charger, and they lasted about 10 hours of usage before needing a charge.
The 13.3-inch Tesla PowerWall charged for 10 hours and 12 minutes.
While a 12-hour battery is pretty impressive, we recommend charging it every other day, as that will allow you to use it as your primary battery.
We were able to charge the Tesla Power wall for more than an hour, which was more than the 11-hour Battery Charger’s 11-minute time.
While most smartphone battery charger won’t make you a star in the app store, the Tesla charger can certainly make your iPhone more useful for longer periods of battery life.
