This charger is great and very unique. It can charge up to 4 batteries at once (Either AAs or AAAs), but it can also charger 9v batteries which is very unique. It can charge the batteries you put into it very fast and I did not have to wait more than a couple hours for them to be fully charged if they were completely dead. Since you can charge up to 4 batteries you should always have a pair that is charged and you can easily swap it out. The charger itself is hard plastic and very rigid, and so, I don’t this will break any time soon. A big selling point of this charger is that it is a smart charger, it is MCU controlled which means that depending on the battery current state is may only trickle charge so the battery doesn’t get overcharged. It also maintains the voltage to each battery so it does not get over-voltaged as well. The charger also have a small screen that will tell you the current voltage and how much each battery is charged (out of 100%). The cable it comes with is pretty well made as well and fairly long too, which means it is pretty versatile and you can choose where you want to put it. It came well packaged as you can see from the photos so you don’t have to worry about it getting damaged during shipment. Though this doesn’t come with batteries if you already have rechargeable batteries this thing is great and well priced.
More info:
SMART & FUNCTIONAL: Independent charging slot. It can random charge up to 4 batteries of 1.2V AA/AAA size, or 2 of batteries of AA/AAA, and a 9V Ni-MH/Ni-CD rechargeable batteries at same time. One battery charged at one time is also workable.
★ LCD DISPLAY: Provided with integrated LCD display for observing the charging process of the batteries directly & clearly, such as you can notice how many each battery have been charged just have a glance of the LCD showed.
★ SAFETY CHARGING TIME: Charging the battery AA/AAA with the current 0.5A, not only charging faster but also better for batteries’ life. Less than 5hrs to fully charged the AA/AAA batteries, and less than 12hrs to fully charged 9V batteries.
★ AC & DC INPUT DESIGN: Applied to worldwide voltage-(AC:100V-240V 50/60Hz; DC:12V/1.5A), Ideal for anywhere in the world. ONLY THE AC CABLE INCLUDED.
★ MULTIPLE PROTECTION: MCU controlled, adopts using -∆V intellectual cut-off charging method, automatically turn to trickle charge, prevent the batteries from over-voltage, over-current or over-heat.
