Top Customer Reviews
A power bank is nothing more than an external battery that you can use to power and / or charge just about any device that has a cord that connects to a power source via a standard USB port. They come in a variety of shapes and sizes and configurations, but there are really only three things to look for when looking at performance. One is the number of USB ports on the device, another is the amperage (listed in milliamps or amps) available through each port and lastly, the total amount of energy stored in the battery, which may be referred to as "capacity" for which the units are usually referred to in milliamp-hours, or mAh. If you have a newer Android smartphone or tablet that you want to charge, then you want a power bank that offers a 2 amp USB port. If you have an iPod or iPhone, you can generally get away with a single 1 amp port, but I always recommend having at least one 2 amp port. A power bank with more than one port will, in theory, allow you to charge more than one device at a time. The thing to keep in mind when shopping for a power bank is that manufacturer claims are often inflated to at least some degree. The most often exaggerated feature is the mAh capacity of a power bank and total amperage output is a close second. Capacity is important because more capacity allows you more device "up-time" per charge on the bank.
Power banks generally use a 3.7 volt battery, as do most cell phones, but the USB standard is 5.0 volts, so the energy must be converted from 3.7 volts at the power bank to 5 volts for output, and then back to 3.7 volts for use by the device being charged. Because of the voltage conversion and other factors involved, there will always be some energy lost, so no power bank will put out 100% of stated capacity to the device to be charged.
Over the past several years, I've been asked by a variety of sellers to test and review their power banks, and while I always did my best to accurately review each item, it was impossible to get precise, quantitative data on the performance of the banks because the only way to do so is if you have proper testing equipment. You can give anecdotal evidence like "It charged my tablet quickly," but you really can't measure the mAh capacity and the amperage put out at the USB ports with any kind of accuracy. Writing informative and accurate reviews is extremely important to me, so I've since acquired testing equipment that allows me to get precise and accurate data regarding the capabilities of a power bank or charger; and I have to admit I'm excited to finally know without a doubt that I'm giving accurate information about a product.
All that being said, here's what I found with the Vinsic 20,000 mAh external power bank...
This power bank has two Qualcomm 2.0 Quick charge ports (2.4 amps), a green LED power percent display, touch power on feature, and measures 6.4” x 3.3” x 1”.
► Testing Qualcomm Quick Charge ◄
Because power bank technology is constantly changing, I occasionally must change my testing methodology. In the case of this power bank, I had to find a way to test and compare the Qualcomm Quick Charge feature. The best way I could think of doing that is to test the amount of charge increase in the one Quick Charge certified device I have, an ASUS T100 tablet, and then comparing that to various other chargers and power banks. I have a battery monitor program on my T100 that shows actual milliwatt-hours of the battery and when charging, it shows the milliwatt hours gained or lost during a set period. That being said, below is a list of different chargers I tested over a five minute period with the tablet and the milliwatt charge added to the tablet’s battery.
Vinsic Power Bank – 266 mWh
My Favorite Non-Quick Charge Power Bank – 162 mWh
My Favorite Wall Charger – 273 mWh
My Favorite Quick Charge Wall Charger – 281 mWh
► Testing Efficiency or Actual Capacity (mAh) Produced ◄
I fully charged the device, and then using a USB Load Inducer, I placed a 2.4 amp load on one of the 2.4 amp ports and let the test run for five minutes without any issues. I then tested the second 2.4 amp port in the same manner and encountered no issues. Next, after making sure the power bank was fully charger again, I then used the load inducer and a power monitor that measures total power transferred (mAh), and placed a 1.8 amp load on the power bank and let the test run to failure. The power bank ultimately provided 13,720 mAh at 5 volts (18,540 mAh at 3.7 volts) before shutting down. I charged the unit back up and ran the test again, this time the power bank put out 13,816 mAh at 5 volts (18,670 mAh at 3.7 volts).
In summation, this power bank puts out around 93% of its stated capacity, which makes in king of the hill of any power bank I’ve tested previously. I consider anything 90% and above of stated capacity stellar, 85% to 89% is very good, 75% and 84% is average and below 75% is poor. This thing charges my T100 basically as fast as my fastest AC charger and I’ve never encountered a power bank that could come close to that.
I’d give this ten stars if I could. It’s absolutely awesome and has far surpassed any of the 50 to 75 power banks I’ve tested in the past.
🌟 Complimentary Product Received for Testing and Unbiased Review 🌟
To test if in fact this claim is supported I used a current meter and a resistor with 2A and 1A settings. As advertised both ports were able to deliver the rate advertised by the resister. 0.96A/5.13V delivered with 1A resistor, and 1.85A/5.06V delivered on 2A resistor (it is normal to see some loss due to inefficiencies such as heat loss). Attached are images showing the tests.
The battery has a large capacity (20,000mAh) and is fairly large: 6 3/8" x 3 1/4" x 1". It weighs 1 pound and 0.3 oz. It has two ports. Another feature I like is the digital display showing how much capacity the battery has remaining. The display comes on automatically when I charge, or I can see it at any time by pressing an icon next the display. This is external battery does not allow charge through (i.e. it cannot charge while being charged). I have been using this battery for just over 2 weeks as I write this review. It holds the charge quite well (very little loss when disconnected) and the rating to appears to be accurate.
I received this power bank for evaluation and review. It is a good one!
