Talentcell 12V Lithium Battery Pack Car Charger, 12.6V/1A DC 5.5mm x 2.1mm Car Charger Adapter for 3S 12V Rechargeable Li-ion Batteries, Black

I bought this to use with the Talentcell battery to use with my CPAP machine when camping. Works OK.

unfortunately these are complete garbage. i have had 2 burn out for no discernable reason after less than a week of use. even worse when this happens it also renders the attached recharging battery inoperable. unless you want to brick rather than recharge your battery do not under any circumstance purchase this item.EDIT: to give credit, Talentcell has been very communicative and professional attempting to resolve this issue. Although I still would not recommend or trust this charger not to suddenly stop working, I do believe Talentcell are operating in good faith and sincerely interested in feedback and offering a reliable product.

I purchased this for my husband to use with his cpap while camping. He was able to adjust the settings on his machine and he gets two full nights with the battery without having to recharge it. Thus has made camping much more enjoyable for everyone in a two mile radius of our tent... as he snores like a bear without the cpap. Lol.

This is a review for the TalentCell Lithium Ion "Battery Charger" Car charger model. The cigarette lighter charger that should allow you to charge the battery pack from your car. I'm not sure why all of the reviews here are for the battery itself not the charger (which is what is being sold). Having said that, the battery packs are great and if you charge them using the wall charger, they charge up and the light on the charger goes from Red to Green after several hours. However, the light on the Car charger is green and stays green as soon as you plug it in. I have tried it with the battery pack switch set to on (1) and off (0). By the way the symbols are common in electronics as they represent (Binary) digital information 1=On 0=Off. Thus most computers have a symbol which is a Zero with a One in the middle, to indicate this is the On/Off button. At any rate, in either position the LED on the charger never changes color and the battery pack does not get charged even after 10 or more hours. I purchased two of them and neither works. I planned to use these while camping and need a car type charger to recharge the batteries. I originally put this as a 1 star review because both did not work. However, the seller contacted me almost immediately after my posting and is sending me replacements. For that prompt response I will move this up to four starts (assuming the new ones work).

An accessory that does its job.

Charges my TalentCell 38400mAh power bank, but it is very slow and I’m not sure it will even charge my device to full capacity.

It does one thing well: produce 12.6 volts.

My cooler battery charges fine from a wall charger and showing the charging state with blue LEDs blinking on the battery. Got this charger for charging it in the car. The charger's red LED seems to indicate it is charging, but the blue LEDs on the battery don't show any charge coming in.
