While some batteries are charging, it interrupts and resumes the process. the charger beeps constantly and the result does not even show how many mAh has been charged. At the same time, when charging some batteries, it let the cell completely replay to a value of over 40 ° C, which is really not a healthy temperature for charging such small cells. Among other things, the article test function practically does not work. In general, the operation and functions of the charger are completely out of order, and the functions of the charger are completely out of tune, so the charger only looks good on paper.

the discharge function works well.

The touch buttons are definitely not a win. The classic would undoubtedly be more reliable.
voltage measurement is not accurate, even when the battery is already charged and no current is flowing.
the contacts for attaching the article have a somewhat special shape, so the articles do not hold the best ones. They easily lose contact and the batteries in the charger float slightly. I haven' t encountered this with other chargers.

although a little more rugged control but it works exactly like me. Money well invested.
there is no information about the required power / how many watts should the source have to work correctly.

He seems to do almost everything in the description except for one thing
clear display
You can use a charger for your phone, it doesn' t have its own - I don' t have to pull an extra thing
She failed to monitor the temperature of the batteries and adjust the charging current accordingly. And so much so that the labels from the batteries peeled off
is pretty big

For such a product, a charging current setting would already be appropriate. It monitors the temperature of the battery, but it only does this by calculation, which is highly unreliable and you don' t want to let it charge much without supervision. The charging current depends on the number of cells you want to charge, the type of cell and the source. Classic NiMh cells are capable of charging up to 1A per cell, which is ok for LiIon batteries, but for NiMh cells especially AAA size and small capacity, it can be as much as 0.3A. This can be solved by using a weaker source, for example 1.5A 5V or even 1A 5V (older weaker mobile phones), the charger then works with what it gets from the source and the current to the cell is reduced proportionally. This thing must be taken as a feature, however I would expect the product with its own source and adjustable charging current manually, as a separate box that can remake the flashlight into a power bank, it has a certain logic and purpose. On the other hand, if a person charges cells in this way even without knowledge of electrical engineering, the charger will not explicitly destroy the cells, but a loss of life must be expected. For me, I' d rather pay extra for a better charger than spend money on new articles. Fortunately, I take care of it with an adequate source, I don' t know for a layman. In addition, the instructions do not mention this problem at all. (Again, I don' t want to hurt the product completely, charging is quite intelligent, when I compare it with chargers ten years ago, so it' s heaven and bagpipes, especially for the money)
charges different types of batteries
it also handles discharging and measuring capacity
the charging current setting is missing and the only way to monitor the correct current is to use another source.

The Duracell 2500 mAh battery is charged to 2800 mAh and the Energizer 2450 mAh is charged to 2780 mAh. The batteries do not heat up until recharging begins.
I can use a mobile charger
charging speed drops
neither the battery nor the charger body overheats. The batteries will not start to overheat until they start to overcharge
cannot correctly determine battery capacity. This usually overcharges.
the end of charging must be monitored by yourself
charging always starts from zero.
It is therefore necessary to select the discharge function before charging.

If you're looking for a reliable NI-MH battery charger, I've not had a better one, li-ion charges as it should, but diagnostics and all that other stuff, I'd rather not talk and have a comparison. For the average user, perfectly fine. Just for info, charging all 4 NI-MH AAA at current up to 1A on a 41 degree battery, 36 on the charger, don't worry, the battery is a Varta recharge accu AAA1000mah maybe someone in previous reviews had a different one. to Li-ion I charged a large 26650 on this charger and also without any problem. I think that for this price you can't get a better charger (compared to SKY RC MC3000), but this is profi over profi.
it's charged as it should be
the discharge is as it should be
battery test, with AAA battery so 2-3 days, I can't imagine to give more
refresch in about twice the time

Charging AA or even worse AAA cells with this machine is suicide, despite assurances of sophisticated charge control that doesn't work at all in real life. The cells will overheat and then the cells will be punctured. I STRONGLY ADVISE AGAINST USING IT IN ABSENTIA !
