From the link on post #1:

"What we want to convey to everyone is that the process of charging a battery is like a dance, and a high-quality charger ensures that the dance is precisely choreographed. It doesn't just charge the battery, but also helps improve the overall performance and life of the battery. The result is a battery that lasts longer, delivers consistent power to your devices, and maintains a higher level of reliability."

Of further interest is that XTAR, in this release, chooses to cite 2 other brands as being the cheapest and lightest. It's not often that we see a company open to even mentioning a competitor unless it points out something inferior.

Yes, XTAR does state that their model MX4 is the best in terms of versatility, reputation and overall value. Less than $20.

We own the BC4 from early on. It is regularly used for son's X-Box controller batteries. Being able to be used as a powerbank is a plus. We have never used it as a flashlight as of yet.
