4-Position Professional Quick Charge and Discharge Technology

This charge means business! It can charge 4 dead lithium double AA batteries in just a few hours! Great for use with portable scanners!

Consistently Excellent Performance! No More Single Use Batteries!!!

Best charger I ever have. This charger gives indicator showing the charging progress, which is great. The charge time is same but that's expected. The battery refresh feature is very useful. I like NiMH batteries due to high safety and good-enough capacity, and I have over 100 NiMH batteries around, I lost track which ones are newly purchased and which ones worn and close to its end of life. The refresh feature would condition the battery and through the process, it measures the total effective capacity of the battery (a 2400mAh rated battery would show 2150mAh after a year)! That's very, very useful to me. I now know which batteries could be used in remote controller (consume less power) and which ones to put into kids toys (drain battery in hours), and which to ditch away. I don't use the USB output feature at all but hey that doesn't hurt either. Another positive mark - This charger is quite - some chargers have high pitch noise when actively charging, and that bothers me when I am working on my bench. This one is quite as a deck of cards. Not all chargers are made equal, and I am happy to say I found the right one for me.

Unfortunately did not provide enough time for further testing, however it charged fast, the charger itself felt like it was made well, & for the short time they were utilized, the batteries held a full charge. Due to no longer needing the product I purchased these batteries & charger combination for; I wound up returning these. However, should I need this battery & charger product combination again in the future, definitely will consider buying them again, but hopefully with a reason to keep them permanently.

I decided to spend a little more on these, and I'm glad I did. There's a lot of crap Chinese batteries and chargers on Amazon these days. We do cabinetry and remodels and are always needing batteries for laser levels and things like that so this is great for that.

The product seems to be very good. The battery drain function did not help me - some of them are faulty. Please note that an adapter is needed for those who do not have an American socket

This is an excellent solution for people who want a simple to use charger without overwhelming screens and data feedback from overly complicated chargers. Those chargers have their place for certain applications, but this one is perfect for electrically challenged individuals. Use rechargeable batteries that it is recommended for and it basically does the function for you. Simply put the batteries in and walk away. That simple. I used this for Eneloop Pro AA and AAA batteries for running ham and GMRS radios. Works awesomely well. Only complaints, but not deal breakers. One is that the USB port on the side is not operational to charge other devices while it is charging batteries. It’s either or, but the extra port is nice to have when the unit isn’t being used for batteries. The second is that there aren’t any mounting holes on the back of the unit to hang it vertical on wall to save counter space. It’s only intended to sit flat on a surface and isn’t very efficient use of countertop or desk real estate, but it’s only a four bay charger so it’s not overly large. I just dislike cluttered countertops and workstations when it can be avoided.

Good investment saves money in the long run like it displays percentage of charge and resets battery memory

The items performs as was described and I have more information when charging the relevant batteries instead of guessing the state and quality of the batteries using a normal dumb charger.

Primero que nada es un Panasonic. Que podrías esperar, electrónica de calidad. Hay cargadores en Amazon desde 400 pesos, pero he tenido varios y a la larga me decepcionan. Las pilas después de un tiempo a veces cargan, a veces no cargan ya que tienen efecto memoria. quería un cargador más "serio" o profesional que tuviera información y algunas funciones avanzadas. este es perfecto, porque hace todo lo que quiero, y además, es marca Panasonic, lo cual es garantía. que me gusta? - construcción robusta, se nota la calidad - se pueden cargar las pilas por separado, no necesitas cargar en pares (como en otros cargadores) - el display enciende en azul, para una mejor visibilidad - indicadores independientes por batería - se pueden cargar AA y AAA - diagnóstico inicial. al poner la batería, se hace un scan y se indica si la batería está funcional o dañada - te indica el tiempo que lleva cargando - te indica el % de carga en tiempo real - te indica el voltage de la batería y el progreso incremental - indica batería dañada - indica cuando la carga está full (completa) Tiene una funcion para hacer refresh de la batería, pero no lo he probado. tengo una batería que se marca como "dañada" y voy a ver si la puedo "revivir" con esta función recomiendo mucho este cargador, vale la pena hacer la inversión en marzo 2024 el costo ronda los 1300 pesos

Très satisfaite de mon achat malgré le prix élevé

Me gustó mucho, te indica la carga de cada batería. También las puede restablecer para borrarles la memoria y que queden como cuando nuevas, aunque esa opción no la he utilizado aún. Es un poco caro pero creo que vale la pena la inversión, aparte las carga más rápido que el cargador normal. Recomendable.

Me encantó este cargador desde hace tiempo estuve buscando uno igual ayuda mucho el Displacía avisándote cuando están cargadas las pilas o ya no sirven
