Poor performance of Choetech Adaptive Fast Charger, 5 port 60 watt

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.

I bought one of these units recently. Mainly to charge my non QC2 device.
I thought I'd get one, for when I get the Note 4 or S6.
Anyway, I returned it, it charged slower than my original plugs.
Hopefully another company will release a multi port charger with QC2 soon.

I'm waiting for these to become available. The 3 and 5 port models look enticing.

Yes, number 3 and 5 is what I'd be interested in too.
Hopefully Amazon UK or similar will stock them.
Thanks for posting.

I actually bought the 5 port model and I believe I'm the only review right now. Works as advertised.

Yes, I read your review and did wonder if you'd written it, as you mentioned Choetech.

[Quick Review] Tronsmart 3-Port Wall Charger with QC 2.0

It's been some time since I've reviewed another Tronsmart product. I got this Tronsmart 3-Port Wall Charger as a review unit almost 3 weeks back and I didn't get enough time to write the review since then. On the brighter side, I'm using this for 3 weeks now, so I can probably be more precise while writing it now. So here it goes...
I'll be splitting it up in following 4 categories and talk about each of them one by one:-
- Packaging & Content
- Build Quality & Design
- Functionality
- Pros & Cons
Packaging & Content
Tronsmart has never dissapointed me in this category, so I do not have much to say here. It comes in one of those recyclable brown box with a printed cover wrapped around it.

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
On opening the box, you can expect the following items:-
- 3-port USB Wall Charger (TS-WC3PC)
- 1 x 6 ft USB Cable (20 AWG)
- User Manual
- VoltIQ Information Card
One thing to notice here is, even though it has 3-ports, it comes with only 1 USB Cable. So, if you're buying it, make sure you have that many spare cables to use it with.
Build Quality & Design
If you're one of those who can't withstand a product with bad finishing, you and I are no different. Luckily Tronsmart understands us and give its products the best quality in terms of material used and overall surface finishing. Here's a look:-
The quality is absolutely fantastic. What makes it even better is its folding type plug which also makes it easy to carry around. It has a green power LED. From the size perspective, it's very small, not OEM Charger small though, but tiny enough to hold it in your palm. Here's a comparison between a Samsung OEM Charger and the Tronsmart 3-Port Wall Charger:-
The in-box USB Cable is a 20 AWG (for high current flow), very durable 6 ft long cable which should do a descent job if the device is to be used while charging.
Functionality
The unit has 3 USB outputs out of which, only one port supports quick charge output at 12V/1.5A while the other two ports are powered at 5V/2.4A each with VoltIQ Technology.
While reviewing the unit, I connected 3 of my mobile phones simultanously to check it's output. First I connected the USB Amp meter to the Quick Charge output which is connected to my Galaxy S6 Edge+. The total power drawn was around 14.76W which is definitely an output we can expect from a fast charger.
Next, I connected the USB Amp meter to a regular port which is powering my Nexus 4. One of the reasons for using a Nexus 4 here is to validate how much current is drawn since Nexus 4 is pretty old device and as far as I've seen, it draws only upto 5V/1A even from its OEM Charger. Like we can see below, the total power drawn is just 5.05W which is almost equivalent to 5V/1A and this ensures me that the VoltIQ is not just a marketing gimmick. I also turned on the display of Galay S6 Edge+ to validate that it is utilizing the fast charging even with all 3 devices connected simultanously (See the Fast Charing in notification ?).
Now, everything was good till this moment except when I went pull back the charger from the socket after an hour, it was HOT. Not burning hot, but you'll definitely feel it when you touch it. Not that it affected any of my devices (none of the 3 devices heated up during charging). It's the same common problem with all the small multi-port quick charge adapters available (3rd party) on Amazon. I did contact Tronsmart regarding the same and they told me that since the adapter is so small, heat dissipation is slow and they assured me that their chargers have passed CE ,ROHS,FCC, PSE etc certifications of conformity and the temperature exhibited is within the safety standard range.
Pros & Cons
Pros:-
- 2 x High Power Output + 1 x Quick Charge Output
- Superb build quality
- Small size with retractable Plugs
- Long and durable USB Cable
Cons:-
- Heats up quickly
- Only 1 in-box USB Cable

Great wall charger horrible cigarette lighter charger. Won't stay in the hole in many cars.

Thanks for review

Choetech NEW Fast Wireless Charger Review

Hey guys, here's my review of the Choetech Fast Wireless chargers.
I was provided these chargers at a discount for my fair and unbiased review. 1st I'd like to thank Choetech for their customer support and openness with my feedback. In my experiences with these chargers I had a bit of mixed feelings. I really really really wanted to like them. And while they worked fine some of the time, I still have been experiencing many issues which I will list below.
I was provided the round charger and Choetech charging adapter, then provided the newer version, the square charger. This was for my Samsung Galaxy S6 Edge+
1. Overheating (round and square) - there have been a number of times I've picked up my phone off of these chargers and it's been 103 degrees Fahrenheit. In my opinion that's too hot and I worry about phone/battery damage.
2. Charging stopping/starting (round and square) - I have mainly experienced this with the round charger. The newer square one still did this but not near as much. The charging would continuously pause and restart as much as 5-6 times in a minute.
3. Not charging at all (round) - sometimes I'd place my phone on the charger and nothing would happen. I'd move it to dead center and still nothing. It wasn't until I unplugged the unit then back in until it started working again.
4. Slow charging (round) - multiple times I'd place my phone on the charger and it would only go up 4 percent in 2 hours...
5. Charging seemed to stop at around 75% sometimes and just stay there. (round)
6. Charging light blinked (round) - not sure what this was about but many times it would just sit there and blink green.
7. Overnight charging seemed to stop (round) - I'd wake up to a blinking light and my phone would not be at 100%. Usually between 75%-95%

In all I definitely feel the square charger worked better, however at this point I can only give it a 6 out of 10. Choetech seems to have great customer service and the build quality of their products look to be great. There just seems to be a few technical bugs that need to be worked out.
That being said, I will say that my Samsung Wireless Charger also experiences a few of the above mentioned issues mainly numbers 6 and 7. So who knows if it's the chargers, my phone, or just bad technology in wireless charging. I will say I'm pretty bummed and was expecting better for a phone I've paid so much money for.

I have been using this pad for a few days now, and I love it. Compared to my OEM Samsung charging pad it is spot on.
Love the build quality and ergonomic design. I appreciate the fact that is very thin and has very sticky pads on the bottom that don't allow it to slide around on my nightstand.
I've even used this in my car and the pad did not slide around or move.
Another great feature is the non-intrusive LED light, because of this it has earned the coveted spot on my nightstand. The Samsung one as well as another QI pad I have both have really bright and obnoxious LED lights. This makes use of them on my nightstand very unlikely. I can't stand that bright LED in my face. Choetech pad has one small LED that can be pointed away and doesn't bother me one bit.
Furthermore, the cable that came with the unit is superb, seriously something as simple as this can really enhance a product. The cable is thick and solid feeling yet very soft and flexible, this is a big plus in my book.
Can't say enough good things about this charging pad, it looks great, charges fast and works well with my S6 and Note 5. Even the packaging was very well thought out, like something you'd expect from Google or Samsung.
Solid thumbs up from me, I highly recommend this product.

Choetech 10400mAh Quick Charge 2.0 USB-C External Battery

I received Choetech's new power bank today. Though this will be an unbiased review, I did receive the unit at a discount in exchange for my review. I just received it tonight, so it'll be a bit before I can get several charge cycles from it and give my full impression, so this post will be updated.
The unit itself is a good size, much smaller than the Ravpower though that is expected as it is half the capacity. This one is definitely pocketable, though you'll notice it since its rather thick and has some noticeable weight to it. It has two Type A outputs- one Quick Charge 2.0 and the other 5V/1A- a Type C input and a Quick Charge Type B input. The build quality is good; it feels like you could drop it a few times and not damage it. The faux silver chamfered edges look nice against the black, and even though the casing is plastic it has a good feel to it. Overall the build construction is good for what it is.
The big disappoint with this is that even though it has USB Type C, it is for input only. It makes us for this slightly by including a 0.5m A to C cable (which passes CheckR, BTW.) You won't get the fastest charge possible though. My phone was at 37% and I got a max speed of 1560mAh, which is to be expected with a compliant A to C cable. After taking a bit to ramp up the power held pretty consistent at 1400-1500mAh.
So far this seems like a nice power bank, but without Type C out there is not much to set it apart from the rest of the offerings. The only real advantage is that it can quick charge at 5V/3A with a Type C charger, but for us Nexus owners the charging is limited. The one USB A output is Quick Charge 2.0 compliant, so if you still have devices that utilize that you can quick charge them still. Choetech says they have a new bank coming out with Type C output, so at this point even though this is a well made bank I'd hold off buying it.

promised update: I used this to charge my phone overnight for 3 nights. the first I was at 18%, the second at 40% and the third I was at 32%. It didn't fully charge the third night, but when I woke up I was at 88% so it likely got slightly higher than that before draining back down. Overall good output for a 10k mAh bank, but I just can't get past the fatal flaw of no USB C out. looking forward to the promised revised version however, with proper USB C implementation this would be a solid bank for a little weekend trip where you only need a couple of charges

Just received mine today! Looks really nice and the size is good too.

heard back from choetech last night and they are waiting for stock of bidirectional usb c chips so they can start producing their new power bank

Dammit I just got this in, can I not charge from the USB C port?

nope :/

[review]choetech 39w 3 port walk charger

After using their single port USB C charger Choetech send me their latest, which has 1 Type C port and 2 Type A ports. The Type C port delivers 5w/3a charging and the Type A ports offer 5w/2.4a max. The C port performed basically the same as my stock 6p charger, and while plugging in devices to the Type A ports caused a slight decrease in the power going to the C port it was only around 50mAh so it was nearly inconsequential. The size on this is small enough that I can throw it in a bag without worrying, and the foldable plug design helps keep it compact. Three ports mean I only need one charger for my phone, watch and Bluetooth speaker making this a great travel charger. Overall I would highly recommend this to anyone looking for a quality charger that can handle both old and new devices.

*wall, lol

<MODERATOR EDITED - SPAM REFERRAL LINKS DELETED>

I pulled around 2600mah, but my battery was at 55-60%. with the stock charger I pulled basically the same

Looks pretty good. The multiple ports would be nice to charge my tablet at the same time as my phone.
ETA: I also like that the plug folds flat, I much prefer that design even if it's a little bigger.
PM sent as well.

I was just thinking about looking for a c type charger on Amazon this morning. Came here first, looks like this would fit the bill nicely.

I meant to purchase a combo pack the last time I saw someone mention their chargers. They were having some special though, I think, where you could get a wall adapter and cable together and get some amount off. If I run into that again, I'll more than likely pick it up. I need myself a work charger.

Got this as well and it is amazing. I received this new charger and the type C port delivers 5w/3a charging and the type A ports supports up to 5w/2.4a max. The C port works perfectly as well as the type A. The foldable prongs makes this a compact design and less risky to damage. Overall I would highly recommend this to everyone.

I just did a charge test with this unit. I have had good results with this one as well as the single port one.
7:28 PM - 3% Battery - 2550 mA in Ampere
8:25 PM - 78% Battery - Didnt check for mA
8:52 PM - 96% Battery - 650 mA
9:12 PM - 100% charged (it finished before this but didnt check the exact time). Likely done before 9 PM
Testing was done with the OEM google USB-C cable

I just bought this charger...since I got a used n6p w/o a charger...I read it was good for the n6p...is it true?

Just got my 3 port. I used it today and it worked great. Rapid charging worked as expected.

Thanks for the info man.

Looks like there is still no EU version of this charger, I'm sad
