LiitoKala Lii-600 18650 Battery Charger Smart Universal Charger LCD Display f...

I recently purchased the LiitoKala Lii-600 charger, and it has exceeded my expectations. The touch-button interface is intuitive, and the LCD display provides real-time information on each battery's voltage and charging status. The charger supports various battery sizes, including 18650, 21700, and AA, making it versatile for different devices.The 3A fast charging capability is impressive, allowing for quick and efficient charging. Additionally, the charger offers battery capacity testing and repair functions, which are valuable features for maintaining battery health.Safety is a priority with this charger, as it includes protections against overcharging, overdischarging, and reverse polarity, ensuring peace of mind during use.Overall, the LiitoKala Lii-600 is a reliable and feature-rich charger that I highly recommend for anyone needing to charge and maintain rechargeable batteries.

I would like to add two things to the first review by another customer.1. It appears it is possible so manually set the charge rate for each slot. It's in the manual but it's not very clear. But just go through the standard process of inserting your batteries and select the charge rate. Now switch to the slot you wish to change the rate on and hold the MODE button until "Charge" is blinking. Charging will restart and you can select the charge rate. This should make it possible to select different charge rates for all four slots. What you can't seem to do it mix between auto and manual. It's either one or the other it appears.Again it's in the manual; but comes off more a hidden feature easily missed.2. The LCD backlight will shut off after a short time until you press a button. If one wants to leave it on..long press the slot #1 button when the backlight is on. The backlight will now remain on.

Nice charger. Plenty of options for charging. You can choose the desired current to charge the battery safely. Has the test option, and refresh and repair features. One thing I do not like, is in manual mode you can not adjust the current for each slot. Whatever amperage you choose for one slot it will be the same for all other slots. I recommend to charge same type of batteries at once. Mixing different types of batteries is only recommend ed if you will use the auto setting. I am very happy with it. I used it a lot of times and works perfect. Does not overcharge the batteries, does not get them hot and stops automatically when the batteries are charged. It has a beep to let you know the end of charge. I recommend this charger. One thing to notice is the size. It is a bit larger than all other chargers in the market, but it fits a large variety of batteries. Buy it and you will be very happy.

My product died within the first year. The customer service is a joke but Amazon takes care of the issue

Charger recognizes AA Li-ion as 3.70 volts. It shows that the battery is currently at 4.20 volts. The battery is actually at 1.5 volts. The battery an AA Zepath rechargeable 1.5v

Hi there. Just small review because i was looking for some advanced device with be honest basic features:ChargingDischargingTestingRepairing as an optionOf course for AA,AAA and 18650 batteries supportGood to have USB type C, but this is really good to haveThis device is on of the best, with wide range batteries type support, different current, auto and manual modes, and indication ;-)Completely understandable indication, with fully independent channels (differenet modes and batteries) suppport.So, really good device which can satisfy beginners and more advanced users.

Works ok, but makes a big spark every time I connect the AC plug to the wall, which means is drawing a lot of current, when I mean big spark it makes you afraid, the sound is also scary, most likely is the power supply that came with the unit. Very disappointing,Can’t recommend this producto since is a safety hazard. Sad, I wanted to like this unit.

Yes, you can get a cheaper charger to simply charge your batteries. By being able to test the capacity I'm able to satisfy that "is this battery going bad?" itch. If you're like me and have used lithium cells for many years, re-wrap your cells, etc., then you also lose track of how old your cells are and have a mix of newer and older. You can also set the charge rate on this anywhere from 250mA to 3000mA... which (tip)... if you don't need them fast, slow charging rates will extend the life of your batteries. I have not used the XTAR Dragon VP4, which I still own a VC2 that I love... the Dragon looks to be the comparable device and is currently $25 more so I tried this one instead and it is meeting all expectations.
