Popular Mobile Batteries on Amazon Japan, Do they really work? We put the 10,000mAh capacity Batteries to the test
As the Smartphone became the universal cellular device, users came to realize the failing battery life their devices offered. Naturally the demand for a solution was inevitable; the emergence of the mobile battery. There are various types of mobile batteries currently on the market. Some mobile batteries released even exceed 10,000mAh. If you were to search mobile batteries on Amazon, the top selling mobile batteries are the ones with the highest capacity. Some being cheaper than others might make someone wonder, do they really work? It is only natural to assume the worst.
So let’s do the test!
We tested 5 products: 3 best-selling models from Amazon Japan and 2 cheaper large capacity models from retail stores in Akihabara (8,000mAh +). Is the Amazon ranking really accurate? Or is it the same if you purchase a cheaper model from retail stores?
We put these products to the ultimate test, so you can choose the right battery!
