Review on 🔋 EBL Battery Charger Combo: Rechargeable AA Battery 2800mAh (4pcs) and AAA Battery 1100mAh (4pcs) + Charger for AA/AAA/C/D NiMH Batteries by Dan Olsen

alright, so i have a Panasonic brand charger, and mostly nice eneloop and eneloop pro batteries. got this in a kit that came with some EBL brand ones. i am an electronics nerd, i have a degree in avionics, and i geek out on these sorts of things. k, here we go:-when i took batteries DIRECTLY off of my panasonic charger, and put them in here, they continued to "charge" for a while. however, when i checked voltages before and after, there was no change. this indicates to me that not much was actually being done in that time ('bout an hour) that they showed charging.-when i took a battery directly off of this charger, and then put back on, it took at least 10-15 minutes to show that battery as fully charged again. why so long?-i tried to charge three D cell batteries at the same time. it did NOT like that. the left bank display just kept cycling on and of, presumably there wasn't enough juice coming through the charger to keep them lit up. so, this charger does not have the ability to split amperage, it seems, between multiple batteries charging, it just tries to do them all at whatever preset amperage, even if there isn't enough to make that happen.-switched to a higher amperage power supply (2.1amp) and then I could do three D's, but 4 was not happening. I didn't have a 2.4 or 4.8 amp power supply, or that may have worked just fine. Didn't come with a wall wart, so i used what i had.-one of my 3 USB_C power supplies would NOT work with this, and that happens to be my phone's charger, which is the fastest, bestest one i have, with variable output.-batteries didn't get hot while charging, nothing caught on fire, and i'm happy with it overall.
