TAIFU 16V AC Adapter for Goal Zero Yeti 150 200 400 500 1250 Yeti Lithium 400 200X 500X Portable Power Station Sherpa 50/100/100AC PN:31901 22004 23000 Goal Zero Power Supply Cord

I was afraid of incompatibility but it worked just fine.

I bought one, and tested it with the Yeti 1000 at 85%, which it topped off properly. Then I bought a second one to speed up the charging process. It also worked by itself in topping off, and with both together charged 2x faster.But sometime later (after 30 days), when I tried to recharge the Yeti from 55%. Neither one worked, either alone or together. The Yeti's screen showed an initial input that quickly went to zero. Then it repeated this over and over.I'm an electronics engineer, and hooked up a lab DC power supply, with its current limit set to 5 amps. It fully charged the Yeti with no problems. The Lab power supply showed that with the current limiting, the initial charging voltage dropped to 12 volts, which is the normal way current-limited charging works, whether from a power supply or a solar cell array. These units are ordinary constant voltage power supplies, and when a load tries to draw more current at their full rated voltage, they react like it's a short circuit and shut down. They are not designed for lithium battery charging. No way to give zero or negative stars.

It worked for my Goal Zero 1400 but not my 400

Using this to charge a GoalZero 1500. 4 hours of charging and barely to 25% The box portion of the charger is so hot I can't hold it for more than 5-10 seconds. Definitely wouldn't trust it to be charging while I'm not home. Even smells like an electrical fire.

Works well

I used this for another device that called for 15v minimum. When testing the output voltage I saw 15.4 volts when loaded at 5 amps. It is rated at 16v @ 5.6 amps.. close enough.It was a little more pricey than other options but it works.Given the voltage drop (again, not a deal breakers) under heavy load and the price, I will say 3.0 stars; recommended.

This is a great replacement supply it's built very well it works well it doesn't get hot I like it it's a great value for the money easy to use just pluck it in and plug it into your power supply or generator so far, I really like it was a great replacement for my original one that I had that accidentally let the dog eat The power cord is very hefty and so is the plug-in I like it very much highly recommended when you need a replacement this is a good one

Defective, had to return wouldn’t charge the GoalZero Yeti 1400.
