Enjoy the convenience of an all-in-one portable powercell from Ventev. Charge the battery and your device without needing extra cables.

According to 2015 data from the Pew Research Center, 68% of Americans own a smartphone (98% cellphones), 45% own a tablet, 40% own a gaming system, 40% own an MP3 player, 19% own an Ebook reader, 73% own a computer of some kind. With the population of people in 2015 listed at 321,773,631, there are an estimated 218,806,069 smartphones in existence.  Another source Quartz Media LLC, there are nearly as many cell subscriptions as there are people on the planet at ~6.8 billion.  With all of these devices, comes the need to charge them.  Unfortunately, battery tech has not advanced nearly as fast as the smartphone tech. You can find batteries from a few thousand mAh to upwards of 20,000 mAh.  When you get much bigger than that, weight becomes a substantial issue.  I have tested multiple portable batteries, some have been fantastic and some have been a waste of money.  Since the battery tech is mostly the same, I like batteries that offer unique features.

When I travel, I may bring my iPad Air 2, my 42″ Apple Watch Sport and my iPhone 7 Plus with me.  I may also have 3-4 brands of Bluetooth headphones, depending on the length of the trip.  All of these devices require regular access to power.  If I am camping or away from home, they require portable power.  Ventev has a Powercell 10,000+ mAh MFI certified universal charger that has proven perfect for this task.  This battery size is the ideal for travel.

If you assume 80% efficiency, you have 8000 mAh of a battery to charge your devices.  The iPhone 7Plus is 2900mAh, the iPad Air 2 is 7340 mAh and 42″ Apple Watch is 246 mAh.  Having 8000 mAh of power, I can charge my iPhone 7 plus roughly 2.75 times or the iPad air 2 once or my apple watch for an entire month.  With an average days use, I would expect my phone to be at 30% power, iPad at about 50% power and watch at 30% power.  I would figure that a 10,000 mAh battery with 80% efficiency would charge all 3 items at least once, assuming the devices were not at 0% to start with. The 80% efficiency is a commonly reproduced value.  Some authorities even assume you will get only 2/3 of the capacity of the battery, due to conversion between the 3.7V battery and 5V charging circuits.  The increased heat of your phone while charging can be used to explain some of the loss of the battery power.

The Ventev Powercell 10000+ weighs 10.8 ounces (9 oz listed in materials) and measures 2 7/8″ wide by 5 1/2″ long by 1 1/4″ thick.  Before you look at the weight and feel turned off, I want to discuss some of the added features of the battery.  It has a built in Type A wall prong, that will fold out of the way when not in use.  This feature is outstanding in a power pack, as you do not need to carry extra charging gear for the battery pack.  I have a few battery packs that require their own AC adaptor, which adds nearly the weight of the battery to your gear.  Since weight is so important, having the circuit/charging capabilities built into the brick is a very large perk.

Along the top of the battery is a battery indicator, with a small LED display.  This is another neat addition, as many other batteries opt for 4 LED lights.  The percent remaining indicator is a lot more sensitive than knowing if you have 0, 25, 50, 75 or 100% remaining power.  To utilize the power, you can use one of the two built-in cables, one for lightning and another for micro SD.  At nearly 3 1/4″ long, the cables are not that long, and they are very stiff.  While charging on a flat surface, the cables work just fine.  It is not very easy to charge while plugged into an outlet due to the angles of the cables.  This system seems to have been designed for portability, instead of pass through power in mind.

I love the color scheme of Ventev.  The rubberized black body has a pleasant grip feel to it.  Along the edges is an orange color, which is very visible in even low light conditions.  In a dim room, my eyes were not able to see much of the black case.  The orange provided a stark contrast to everything else around it, making it very easy to see.  As a test, I had my son hide two of my power banks in our yard at dark.  One was a completely black PowerAdd 20,000 mAh battery and the other was the Ventev battery.  A few sweeps of a flashlight is all it took to find the Ventev battery. It took a considerable amount of searching to find the plain black battery, as it seemed to blend into the grass/leaves.  If you have ever been primitive camping, the orange color really does make a difference.

Another potentially neat, but impractical, feature of this device is that it can act as your wall charger as well.  The internal circuitry will allow the power to pass through and charge your device and then its own internal battery second.  The output of the included charging cords is 5V/2.4A for the lightning adapter and 5V 1.8A for the microUSB adaptor.  If you are not careful, you will miss another feature.  Along the bottom of the battery is a universal USB A port, which is capable of 5V 1A output.  Although this is not that great of a charging port, it is convenient to have available.  This battery is designed to charge anything that has a USB A power cable.

When it comes to cons of the device, there are a few.  I am not a fan of the turn-on feature of the battery.  If you simply plug the lightning cable into your phone, nothing will happen.  You cannot simply click the power button, you must press and hold the button on the top of the battery. If you forget, you will come back to an empty device and a full battery.  Another negative is the shape of the included cables.  The lightning adaptor has a very boxy end, which will make it difficult in Catalyst, Lifeproof, Element and Apple Battery Cases (not an all inclusive list).  The Apple lightning adaptor is rounded as are most of the better lightning cables.  The square cable did fit into my letterbox defender case on my iPad Air 2 and my iPhone 7 without issue.\

Summary:
I am a fan of Ventev products and look forward to their 2017 lineup. This battery has earned a solid 4/5 in my book, even with the above negatives.  When you consider the decreased weight of the other items you can leave at home, 11:15 pm the benefit of the Ventev Powercell 10,000 becomes even more evident.  I do not think I will charge the battery and the phone at the same time, as there is no good way to conveniently do that.  The retractable power prong feature is important, I really like the number indicator instead of the 4 circles, I love the included charging cables (despite the short length and the boxy ends) and the weight is not that bad for a 10,000 mAh battery.

As a final test, I had my iPhone 7 plus at 41% battery power at 10:04 PM and the battery bank at 100% power.  I checked it at 10:45, the phone was at 80% and the bank was at 71%. At 11:15 pm the iPhone was at 100% and the battery at 60%.  My iPad Air 2 was at 40% and when I awoke at 5:30 am, it was full with 30% Ventev battery remaining.  Overall the battery seemed to do quite well and does a great job at providing readily available power for your own the go lifestyle.
