Review: GONGNIU – USB Car Charger

image_thumb Review: GONGNIU - USB Car Charger

This is a quick post about something I found on So, first I was looking for a car charger that would fix my problem where I use my GPS on my phone and unfortunately, my car charger would not charge my phone fast enough so as I’m using my GPS, my phone is also dying.

Previously, I purchased an inverter, but I found that the inverter was a little bit noisy and it took up more space that I wanted to offer.

On Amazon there was a car charger from GNCB that boasted about ‘blazing charge times, reporting that it’s compatible with USB-powered 5 V devices. The price to Amazon was only about 10 bucks and with free shipping, I thought it was an easy deal.

Device Packaging

I ordered my 3.6A dual-port USB charger through Amazon. The item had free shipping and the day after I ordered the item, it showed up. I must’ve been really close to a distribution center (I guess).

The item showed up in a bubble wrap package. Upon opening the package there was a small box inside; very sturdy. When you open the box you see the car charger and you’re thinking that this is just a little cheap thing, but actually this little sucker’s heavy. Much heavier than you would think it would be.

Inside the box, the car charger is packed very tightly in some high-grade foam. The car charger comes with a USB car charger user manual.

Initial impressions

I have to admit when I order the item I didn’t think much of it. I mean what can you get for $10? But when the item showed up, I liked the packaging of the box, I liked the high-grade foam it was packaged in and when I picked up the car charger itself, I was really caught off guard by how heavy it was. This is not a thin piece of metal with nothing in it, it’s jam-packed full of stuff.

People often opt for the highest current available as this will charge their devices the fastest. But if the current on a phone charger is too high (4.8A), it will actually overheat the cell phone battery, leaving it vulnerable to damage and ineffectiveness over time. If the current on the battery is too low (3A), the phone needs a much longer time to charge completely. Having a middle current (3.6A) is the safest option.

Again, the item was only about $10 even. It has a 3.6A charger has an IQ chip that can identify the device it is charging and adjust itself to match the optimal charging.

It even has a capacity of 2.4A in one port and 3.6A total, it can meet the charging demands of most USB powered 5V devices (iPhone 7, 6, Plus, iPad, Kindle, Samsung Galaxy S7, S6, Edge, Note 5, LG, Nexus, HTC, GPS units, smartwatches and more). It can even charge the newest type-c powered Mac Book.

It also won an iF Design Award. I wasn’t sure what that was, so I just Google’d it. Basically, if you are really creating change and making things with bold design; basically doing it better; that’s what this is. That was a cool thought for me.

For this post, I was thinking about doing like an in-boxing video, but there’s nothing to it; it’s very simple.


On Amazon’s website for this item, some of the features were fast charging times, smart charging technology, dual USB efficiency and protection features such as overvoltage, over temperature, over current and surge protection. At least 5 things to help protect your vehicle and your device.

Compared with a 4.8A, a 3.6A car charger controls the temperature better, ensuring it always maintains the safe temperature range (40 degrees or below). This prevents the car charger from overheating (bad for your device and vehicle). The 3.6 A charger provides a safer charging environment than the 4.8A, thus a longer life.

A lot of dual USB car chargers are available on the market and other chargers available often have different currents coming out of each USB port.

So plugging your device into the wrong port in such cases will not only affect the charging speed but could also damage your device. This charger avoids that problem. The maximum output current of both ports on a 3.6A car charger are 2.4A, and because of the IQ chip, it can identify your device, it doesn’t matter which port you use. This allows you to charge two devices at once, knowing that the charger auto-adapts to the proper output (per device).

The only thing I really want to mention here is that with my experience, I don’t have an issue with my phone dying as I’m using the GPS, or using my phone for other activities; which was the main purpose of purchasing this.

Not only does this car charger have one port, it has two. You can charge multiple devices on it at the same time. Also once the car charger is plugged in, it has an illuminated ring only around the car charger to let you know that it’s working. And when your device is fully charged, it stopped charging.


  • I love that this item gives me the compactness and the power that I’m looking for to charge my smartphone.
  • A higher power conversion rate reduces battery loss and increases charging speeds. The average power conversion rate for other car chargers in the industry as a whole is 80%. The power conversion rate for this 3.6A car charger is reportedly 90%; very cool.


  • This is not really a negative, but I wish that this particular car charger included a short USB cable; luckily I had a short USB cable laying around.


I can’t believe I’m mentioning this again, but this device is small and compact. There’s a lot of things inside this thing and when you first get it I can’t stress to you how much you going to be shocked at how heavy this thing is. I guess it’s a testament to how much technology is packed inside to give you that charging power. I consider this a confident buy and for roughly $10, it’s no big deal.
