[Galaxy Note 4 Accessories] taiguy:
I've been a fan of Anker chargers (and other products) as they tend to be high quality and fairly affordable. I have several of the 5 port chargers floating around my home and office that I use to keep various gadgets juiced up throughout the day. I was hoping to find a multi-port charger that was also Qualcomm Quick Charge 2.0 capable so I could bring it with me when I travel. Choetech is the first company I've found on Amazon that advertises a multi-port charger with 2 QC 2.0 capable ports, so I picked one up.

Physically it's about the same size as every other multi-port charger on the market. What's immediately obvious as different though is how light the unit is. It weighs in 5.6 oz (158g) which is less than half the weight of the Anker 60W charger which competes head to head. In this case, I don't think that's a good thing. I haven't cut it open yet but I'm guessing it doesn't have the proper internals to handle power. The other weird physical attribute is that it has recessed USB ports. The actual ports are sunken in by a fifth of an inch (half a cm). I guess the cables can still make contact however, it's a puzzling design decision as you'd imagine that the more contact area the better for power transfer.

Something odd I noticed right away is my Note 4 wouldn't consistently register the charger as fast charger. I swapped out cables, tried unplugging cables from the other ports, jumped and spun around a few times, etc. With my Anker QC 2.0 charger, it would register as a fast charger every single time. I first thought something was amiss after leaving my 2013 Nexus 7 attached to a "standard" port for several hours and then came back to find the battery percentage had only risen 16%. That's really really low.

I reached out to Choetech customer service and they sent me a replacement unit citing the original unit as faulty. It shipped directly from China and took a few weeks. Comparing the two chargers side by side it's clear they've been making small changes to the text on the unit, font size/weight, as well as changing the stated power output from the fast charge ports. At the end of the day it doesn't matter though.

So I tried to be fairly rigorous in my testing and tracked battery percentage over time as well as charge rate over time. A real QC 2.0 charger will hit a charge delta of 80% per hour during bulk charging and taper off as the battery nears full capacity. The Choetech charger comes in at a measly 10% per hour. I put it on at 40% battery and it took all night to get to 100%. You can see from the graph that the charger behavior is to switch on an off instead of providing a clean source of power.

I've attached the same graph (same phone, battery, cable, etc.) with the same axes and time scale but hooked up to a standard charger (non QC 2.0) and it hits a 50% charge rate easily before tapering off. I've verified across two units and two different devices that the Choetech charger is a complete sham when it comes to meeting its advertised specs. I ended up returning my original unit to Amazon and the 2nd unit to the seller in New Jersey.

Reading through the reviews on Amazon, either they're shill reviews or they're from people who haven't actually taken a hard look at what the charger is doing. I'll admit, it does seem to "charge" your devices, but at a snails pace.
