no recomiendo comprar este cargador inteligente. Lo compré poco más de un año atrás conjuntamente con una linterna HC68 y baterías. Lo habré usado una treintena de veces y ya no funciona. Como lo compré desde el exterior no me compensa reclamar garantía (aunque ya estaría fuera de garantía que es de un año) dado los costes de transporte. Cargadores genéricos me han durado más que este.
Ya a los pocos meses de uso cargando una batería NiMH AA sentí olor a quemado y fui a ver el cargador y me encontré con un recalentamiento de la batería que afectó la capa externa que recubre la misma batería y afectó también el propio material ABS del cargador quedando quemado y deformado parcialmente. Seguramente fallaron los mecanismos de seguridad del cargador que debió cortar la carga para evitar esa situación. El cargador siguió funcionando pero al año y un mes no encendió más sin ninguna razón aparente.
Otro punto negativo es la conexión micro usb muy lábil.
I do not recommend buying this smart charger. I bought it a little over a year ago, along with an HC68 flashlight and batteries. I have used it about thirty times, and now it no longer works. Since I bought it from abroad, it is not worth claiming the one-year warranty given the shipping costs. Generic chargers have lasted me longer than this one.
A few months after I started using it, I smelled something burning while charging an AA NiMH battery and went to check the charger. I found that the battery had overheated. This affected the outer layer covering the battery itself, as well as the ABS material of the charger. The charger was burned and partially deformed. The charger's safety mechanisms should have cut off the charge to prevent this situation, but they probably failed. The charger continued to work, but after a year and a month, it stopped turning on for no apparent reason.
Another negative point is the very unstable micro USB connection.
The 21700 battery charger works as it should,
If you use these batteries every day like me it’s a no brainier,always have a battery ready go with this charger,highly recommended.
Customer support is outstanding and product offerings great.
I bought this product because the web site says it is USB-C. It is NOT! Even Nitecore's website pictures show a Micro USB jack, which is what mine arrived with. The charger works, but now I have to change my AC adapter and car cables. What's going on here? Are there two versions out there?
I gave a good 3 months plus before I decided to review. Part 1 is, I received a defective unit. They sent me a replacement without asking for the defect, so my rating is much higher for this reason. Unless I'm doing something wrong this new one is heading towards the same issue as the first one. The past month the right side only shows 2 bars, says good, but does not charge even when I take the left side out. So basically this is now a single battery charger which is not ideal as my device needs 2 batteries to function. I have used other outlets, and 4 different battery brands and they all have identical issues. really a shame because the first month was flawless and you cannot beat the price. But maybe that is the issue. You get what you pay for. I am not saying do not shop Nitecore. But I am posting for other people researching chargers. maybe I am the only one at the moment........
