If you’re like me, you’ve probably been in a “power pinch” at least once or twice. It happens all the time when I’m visiting a coffee shop and I get that seat with no power outlet. Now, there’s a device that can solve that type of problem.

A portable battery bank with a built-in AC outlet is a must-have device for those moments when a power outlet isn’t nearby and you need some electric juice. It’s handy for everyday situations and especially for travel.

I’ve been on the search for this type of device for a while.I recently purchased Ryoko’s Jack Power portable battery during Amazon Prime Day. I had actually been looking at some similar devices and needed something that checked several boxes for me. Here’s what I recommend considering when you look at these portable batteries:

Capacity: I was looking for something that holds at least 25000 mAh. This is a measurement of the battery’s capacity. If you’re looking for more than just a quick charge for those power hungry devices, I recommend 25000 mAh as a starting point. The capacity on this Ryoko battery pack is 27000 mAh.

Weight & Size: You don’t want to be lugging around a brick in your backpack! Expect a portable battery with an AC connection to have some weight to it, but look for something that doesn’t get overly heavy. Ryoko’s Jack Power is 1.6 pounds.

Wattage: Make sure the portable battery can handle the types of devices you want to plug in. The battery should indicate it’s maximum output in watts. For instance, the Ryoko Jack Power has a maximum output of 85 watts. That’s enough to power my Macbook (50 watts) and even a 42-inch LED TV (80 watts). Look up the wattage of the devices you want to power before buying a battery to make sure you’ll get the power you need. One thing I love about the Ryoko Jack Power is the display that tells you how much power you are drawing from the battery in real-time.

Additional Connections: Look for a battery that offers you multiple charging methods aside from AC. Ryoko’s Jack Power battery has two USB-A ports and one USB-C port. Theoretically, you could charge your new Macbook on USB-C, a couple of phones using USB-A and another device in the AC outlet at the same time! Expect the battery to drain quicker though as you plug in multiple devices.

Hardware: Pay attention to the battery’s build. I love that Ryoko’s Jack Power has a fan to disperse heat. It feels solid and looks like it’s constructed well. I also love the display that shows battery life and real-time usage stats. Pass through charging is great for chagrin the battery and a device at thes same time.

If you’re in the market for a battery, do a little research on the company. One of the other batteries I was considering was RavPower’s portable AC battery, which offered slightly more capacity and it was a name I recognized. Ryoko appears to be a company out of Japan – I had never heard of them prior. After finding out a little more about the company, I felt good about moving forward with the purchase and the price was exactly what I was looking for in a first battery pack.

If you’re looking for something more heavy duty, especially for camping or the outdoors, you can find several batteries online with much larger capacity and higher wattage ratings. Also, some companies make portable batteries that can jump-start your car battery. That’s another great tool to have in your arsenal!


Corrections:
mAh – milliamp hours not milliwatt hours.
This product appears to be made in China, not Japan.
