Good charger, bad service. (Good service...read the review)

UPDATE: Anker contacted me a couple days later and promised me a completely fixed unit. 2 days later I see a package in the mailbox. I didn't hesitant to throw it on the electronic load and plug it into the car for a good drive. Lo and behold, everything is fixed. The center spring was less "springy" the side springs were hard as a rock, and the thermal design was much better. At 10v 3 amps the charger is equally hot (a good thing because the heat is actually getting out of the plastic case). It held a constant 4.8 amps at 5.03 volts for 8 hours. The charger is working fine without even picking up a screwdriver. Anker still hasn't failed me yet, words from a long time customer studying electrical engineering.

To start, I need to explain why it is getting 3 stars. The charger is built extremely well on the component level, but Anker’s customer service and the lack of attention to detail semi ruined this charger for me. Let me explain what happened.

I bought the charger and it came in a week, pretty ridiculous when i’m located in the same state as Anker’s shipping dept. I have Prime, but this isn’t a prime item.

Then I plugged it into my car, all works fine didn’t notice anything. Drove around and my phone started to vibrate like crazy, after some searching around, I found out that the center spring was way too strong. The side springs are too weak, and its making intermittent contact with the 12v socket.

I asked on Amazon if anyone has had this issue, and sure enough some people did. So I contacted Anker at support@ianker.com

They said I will need to ship it back, then when they receive it, they send another one. The turn around time was too long so I tried to just return it on Amazon. They didn’t let me so I called Amazon customer service. They refunded my money and let me keep the charger.

Instead of letting it go to waste, I wanted to fix it. So here is the charger in pieces and under some extreme testing.

You can see the Input voltage of the charger I put at its min voltage of 10v. It draws quite a bit of current. 3.07 amps which turns into 30.5 watts going into the charger. However only ~25watts come out. You can pretty much calculate the efficiency right there at around Efficiency = (VoutIout)/VinIin Which turn out a 82.2%

You have to trust me here but I did the same test on the high end, 24volts. The efficiency was 81.8%

The design and layout of the circuitry is not bad at all, although i couldn’t find a datasheet on the main chip MPSF14/M5402M, everything else is quite high quality. You have a good quality solid state capacitor, which is rated 2000 hours at 105C. I have done a burn in test with this charger. 12 hours at full load. It got extremely hot but it’s all working still.

Modifications I have done,

Cut the center spring 2mm shorter, cover the whole inside with thermal pads, to actually get the heat out. But I have to give Anker credit for the small piece of white thermal pad already in there.

Build quality is pretty nice, the inductor is siliconed, solder joints looks good.

Bottomline is, if this charger fits your car. Then your golden, if not and you don’t know how to take it apart. Then your screwed.

FYI Both the Anker 4 port 48w and the old 24w power iq fit in my car’s 12v socket.
