The charger is not bad, you can get it at promotional prices, especially in bundled products. But she also has her downsides; more expensive chargers are better. Does not charge lithium iron phosphate, there is no recovery mode, it overheats the batteries it charges. It has not small sizes.

The product arrived quickly and in perfect condition in my country. The size surprised me because I thought it would be smaller. The equipment appears to be of good quality and charges many types of batteries, in addition to having a function that few chargers possess. The screen is very clear and sharp, which makes it easy to view all the information. Send the version I requested, which comes with the cable and power supply. I paid a very low amount using coupons and coin discounts, so it was really worth it! Now I need to see the durability and if it will present issues in the long term. But considering the low price I paid, it was worth the purchase. I thank the store and AliExpress for the excellent service, as always! Very happy with my new purchase!

The charging and testing device is larger than expected and well-made. I installed 4 lithium batteries and 4 alkaline batteries simultaneously, and they charge automatically while displaying information for each channel. Interestingly, the two Energizer AA alkaline batteries that I purchased a while ago, with an expiration date of December 2031, show an error when fully charged. A sign appears. And is the power-saving mode the default, or does the screen that appears during operation automatically turn off after 30 seconds? This product's power connection is not made to a PC or laptop's USB 3.x (5V 2.0A) port; instead, it was connected to a separate multi-socket outlet using a 5V 2.0A / 9V 1.67A DC power adapter provided by an old Samsung phone and operated that way.

The charging speed is fast, so it's useful when I'm in a hurry. It also has overheating and overcharging prevention functions, so you can use it with peace of mind. It's compatible with various devices, practical, and compact in size, making it easy to carry. I am satisfied because the LED indicator makes it easy to check the charging status.

I have the Lii-500, but since it doesn't charge 21700 batteries (in principle, it can be forced in, but it deforms the positive contact, I don't recommend it), I had to take this model and I don't regret it. It performs its tasks well. But I had to disassemble it to reduce the sound of the buzzer by half. There is heating when discharging the batteries, but it's not critical at all, in short, it's okay, thank you to the seller.
