AC/DC 4.2V 2A Power Adaptor Lithium Battery Charger Single String Polymer Battery Charger 18650 Lithium Battery Charger Full Stop Automatically

I got this to replace a nearly identical unit that I wrecked accidentally. I allowed the original to overheat until it failed due to my own carelessness. I was delighted to find quickly on Amazon this replacement with the same specs and form factor.

It simply worked reliably and did exactly what we needed.. We lost the charger for a lithium battery powered home appliance, and we got lucky with this as a replacement !

Works ok just not enough power that it takes 6-9 hrs to charge 2 batteries instead of 1-2hrs like the original plug

It is an exact replacement for a bicycle light that had a failed charger, I knew the voltage and amperage would be the same because I searched for that, but it is the exact same perfect unit.

We have a large patio umbrella that has built in LED lighting. This is an exact match voltage/amperage for the power adapter that shipped with the umbrella, and works well....until it doesn't. At best I these last about a year - and I bet it only gets used for a few hours once or twice a month. Yes, it's outdoors - but it's shielded from the sun/rain by the deck. I have learned to caulk up all the seams after one obviously had water intrusion - but the last one to fail was perfect inside - no signs of moisture - or any burned components - just dead. I would give it less stars but it's cheap enough to just keep some 'in stock' and replace once a year. Plus I'm sure outdoors wasn't what it was designed for no matter how well I have it protected. Shame I can't find a high quality unit with the same voltage/amperage.

I bought this to recharge a rechargeable lithium light that I bought at an auction. Works just the way it's supposed to and keeps the light charged.
