We take our phones everywhere and constantly rely on them as a lifeline to the world. As a result, a plethora of portable power banks and accessories for holding and propping our mobile phones has exploded with options. Einova thinks they have a solution that solves several problems at once with their Einova Power Ring Qi power bank. Is this the solution you’ve been looking for? Read on to find out!
The Einova Power Ring is designed to be attached to a Qi-enabled smartphone or its case to provide wireless charging to your phone. It has adhesive strips that secure it to your phone or case, but you shouldn’t peel the adhesive until you’ve figured out how to line up the bank with your phone’s Qi charging area.
I have found my iPhone 11 is very finicky about making sure the bank is lined up perfectly, so you definitely want to make sure you have it right before you commit with adhesive!
Along the bottom of the Einova Power Ring, there are four LEDs that let you check the battery level as well as a power button and a USB Type-C port. Otherwise, there are no ports anywhere, so you can’t share the battery with more than one device.
Besides charging your phone wirelessly, the Einova Power Ring also has is a flip-out ring on the back. It pops out and can double as a kickstand or as a hook for your finger to make your phone grip more secure. The ring hinge has just the right amount of stiffness that it holds the ring in position, but it is smooth enough that you can set it one-handed.
I did note that the Einova Power Ring got a little warm with extended use. Einova says it should give you up to 3 hours of extra battery life, depending on your phone. The actual battery capacity is 1,500mAh, so it won’t charge your phone three or more times as some power banks can, but it will keep it from dying if you’re away from an outlet for a while!
I liked the Einova Power Ring, but it feels like a very niche power solution. I couldn’t attach it to my regular iPhone case because I use a rugged UAG case. I did stick it directly onto my phone to get a sense of the size and feel. It works well, but I found it to be awkward and impractical for my purposes.
The Einova Power Ring basically doubles the width of the iPhone, and I don’t usually need a kickstand, so it felt like I was making more tradeoffs than I would with my usual strategy of plugging in an external battery. And because the battery capacity is relatively small, it means I’ll need to keep a USB Type-C charging cable as well as my regular Lightning cable handy to keep everything charged daily. Obviously, if you are an Android user this won’t be an issue.
With that said, if you are someone who doesn’t mind changing out phone cases when needed, the Einova Power Ring might be a good option for creating a “charging case,” one that you can pop on when you know you might be out and about for longer than your phone’s battery would usually last. Having the battery attached to your phone case might be more convenient than having to carry a separate portable battery pack.
So the Einova Power Ring may not be a good option for me, but it may be perfect for you if you use a thin and flat case and you like having a built-in ring for holding your phone or for propping it up when it’s not in hand. If you are an Android phone user, it will mean that the Power Ring is rechargeable with your usual charging cable.
The Einova Power Ring comes in ten color choices, and at only $39.99, it’s an affordable and simple solution. If you’d like a battery that is as simple as “attach and go,” the Einova Power Ring should be on top of your list.
The Einova Power Ring sells for $39.99; it is available directly from the manufacturer.
