[Mobile Battery] What is a semi-solid battery? Have you heard of the "SOLIDZ Power Bank," which is thinner than an iPhone?

The author has come to think that smartphones have become so essential that life would be unmanageable without them. That's why I pay attention to choosing mobile batteries as well. It’s small and has sufficient capacity, and on top of that, lately, “safety” has become essential too. The semi-solid mobile battery "SOLIDZ Power Bank Model QT" seems like it will be my lifeline.

The mobile battery also wants to focus on "safety"

The "SOLIDZ Power Bank Model QT" is the first wireless charging model in the semi-solid mobile battery SOLIDZ Power Bank series. It has a capacity of 5000mAh and supports up to 20W, while maintaining a thickness of only 6.8mm.

When using the mobile battery stacked on a smartphone, the thickness is always a concern. Even if you can charge without a cable, it can be a bit cumbersome when holding it in your hand if it becomes too thick. At 6.8mm, it seems like it can almost feel integrated with the smartphone.

Just stick it on and charge

For MagSafe compatible smartphones, it adheres with magnets. You can charge simply by stacking it on the smartphone without needing to connect a cable. It also supports simultaneous charging of two devices using wireless and wired connections.

The author often continues to use their smartphone for taking photos during interviews, checking maps, and looking at social media. It's very appealing to be able to hold it while charging without worrying about the battery status.

What is a semi-solid battery?

The SOLIDZ Power Bank series features a semi-solid battery. Its structure significantly reduces the proportion of liquid electrolyte, making it resistant to ignition during destruction tests such as being punctured, struck with an axe, run over by a car, or bent. Mobile batteries are items that we carry in our bags almost every day. It seems that the standard will shift from choosing based on thickness and capacity to selecting based on the type of battery used inside.

Recently, regulations regarding mobile batteries have tightened even on airplanes. Those that use semi-solid batteries to reduce the risk of ignition are points of concern as they are tools that are used constantly.

If you're going to carry it every day, lighter is better.

The capacity is 5000mAh, with a maximum output of 20W. The SOLIDZ series also includes models like the Model FT, which comes with a USB-C cable, while the Model QT is a type focused on wireless charging and thinness. Since I use my smartphone for long periods, I use the mobile battery not just for emergencies but for daily use. That's why I appreciate its thinness of 6.8mm, considering it spends more time in my bag.

No need to connect cables, just stick it to your smartphone. When you're done, just put it in your bag. If it's this easy, I might not have to worry about, "Is the battery at 13%... will it last until I get home?"
