Been using it for a few months now.ProsHas two ports for micro usb and type-c cables supporting most of the charging cables.Quick charge. Usually takes around 15-20 mins to completely charge.Charge indicator. Displays the charge in cell in form of four bars 25% 50% 75% & 100% which is quite handyConsNeeds a cable and adaptor to connect to power supplyDisplay meter can be buggy sometimesSo far has been working satisfactorily.

I purchased the Ultra Fast Rechargeable Battery Charger with AA and AAA batteries (4 included).The charger itself is excellent. I tested it with two other rechargeable batteries, and it worked perfectly and charged them quickly. The display works well and shows the charging status clearly.However, one AAA battery included in the package is not charging at all, even after multiple attempts. This was quite disappointing, as it failed after the first use.Overall, the charger performance is very good, but the quality of the included AAA battery needs improvement.

Super

Charger does charge battery but green light and battery indicator is always on. Battery self discharge is very annoying, they just doesn't hold. better to go for panasonic or duracell with a lower mAh but low self discharge.

Very useful product.

I bought the AA x 2 and AAA x 2 pack with the superfast charger. I dislike this and it is better to purchase a Panasonic Eneloop battery + charger bundle.Pros:The look is good, and so is the charger display which helps. There is a small booklet in the plastic box which says that a AA battery should be charged for 1.6 hours and AAA for 1.1 hours. There are battery capacities as well which gives you an idea over how much time is required for charging. The pros end hereCons: (more important)My purpose was to use these batteries for my wireless mouse / keyboard and other similar devices. Purchasing Duracell batteries was getting expensive and so i bought this. The cons are as follows:1. The batteries are not 2800 mah (AA) and 1100 mah (AAA) respectively. They are probably much lesser than that. My wireless mouse runs for just 8 - 10 hours before showing me the low battery light on the AA battery. A duracell battery of the same capacity runs for months before running out.2. The amazon description says 16 hours of charging is required whereas within 2 hours the charger display says fully chargedI tried retaining the batteries plugged in to charge for 16 hours. There was no difference. It was the same as charging them for 2 hours and using them for a day. This is very frustrating. Either there is some fundamental flaw in these batteries + charger (or) i am using them wrong.

It's a good fast nimh and nicd usb battery charger. I didn't notice heating problems. But if you charge your battery one or two more times after full charge, the battery charge lasts longer. It can't detect good or bad batteries (I saw in my case), and that's good for me and others also, who are using their bad batteries (in clock etc). But the combo batteries ie 2 AA and 2 AAA, is not as good as new ones (in my case). Battery manufacturing is current, battery is fully charged (4.2 v), but charges very quickly and doesn't hold charge as a new envie nimh battery purchased saperately.

I use rechargeable batteries in all remote, clock, keyboard, camera etc. I tried many kind of chargers. But this one was the best it even charges 1 battery. Thank you.
