As 1.5V lithium-ion batteries become more popular, many people are using them in different devices. Therefore, they may want to test the capacity of these batteries to ensure their performance meets expectations. Unfortunately, regular battery chargers often do not provide this functionality.

To meet this need, XTAR has launched its latest charger, the VX4 Visible Mixer. It’s the first capacity tester designed specifically for rechargeable 1.5V Li-ion batteries.

The Widest Compatibility for Most Popular Batteries

The VX4 is extremely versatile and supports a variety of battery types and sizes. From AA/AAA 1.5V Li-ion batteries to 10440-21700 3.6/3.7V Li-ion batteries, and even AAA/AA/A/SC 1.2V Ni-MH batteries, it is equipped to handle them all easily.

In addition to the standard charging modes, the VX4 also offers a LiFePO4 mode to charge 3.2V LiFePO4 batteries. This flexible charging feature caters to the different needs of users.

The First Capacity Tester for 1.5V Lithium Batteries

This feature can help you detect exaggerated capacity ratings in new batteries and evaluate the remaining performance after battery aging, helping you in timely replacements. VX4 can test the capacity of popular batteries on the market, and it also offers a breakthrough feature: the ability to test the capacity of rechargeable 1.5V Li-ion batteries. Equipped with a LCD screen, it offers users a clear view of charging status, empowering better control over the charging process. Together with VX4, managing charging becomes worry-free.

That’s not all. After completing the capacity test, just click the “mAh/mWh” button to switch directly to energy display in mWh, providing a more intuitive capacity representation. It has been proven that this feature is particularly convenient for devices with specific energy requirements, ensuring batteries are optimally utilized.

Smart Charging Process Making Charging Easier

You just insert in the battery and let the charger do the rest.

1) With a USB-C input port, it is versatile for charging anywhere. Coupled with a 20W PD adapter, a single slot can reach a maximum of 3A charging current and fast charge a 26650 6000mAh battery in 3.3 hours, significantly reducing wait times.

2) VX4 automatically matchs the optimal charging current based on various factors like battery, quantity and internal resistance. For users seeking more control, we’ve added a manual current selection function . This gives more options and improving the overall experience.

3) Unique CVSA tech for Ni-MH batteries and the 3-stage charging method for Li-ion batteries, it ensures higher accuracy of full-charge detection, faster charging, and extend battery life.

Safety Design and Low Voltage Activation

Aside from charging and capacity testing functions, VX4 also boasts higher activation rate for over-discharged batteries, saving money and energy. It also features multiple protection mechanisms to prevent overcharging, over-current, and other potential risks.

With the increasing popularity of 1.5V lithium batteries, the need for accurate capacity testing and wide compatibility has become critical. With VX4 Visible Mixer, you can say goodbye to batteries with unknown performance and hello to a more reliable charging solution.
