Vinsic Alien 20,000mAh Ultra-slim Power Bank Review
      #48404 - 08/12/15 07:14 PM

The Vinsic Alien 20,000mAh Ultra-slim Power Bank is a portable battery that has one of the highest capacities to date and it's surprisingly slim, though not ultra light. The 20K battery can charge any phone several times over and even a 10" tablet twice and more. The Vinsic battery stands out with a precise battery level indicator and its affordable price. The battery comes in four sleek colors: Grey, Silver, Golden and Red.

With an iPhone 6

The Vinsic Alien 20,000mAh Ultra-slim Power Bank isn't small but it's very slim. It measures 6.81 x 4.72 x 0.47 inches and it weighs 1.2 pounds. The one-piece aluminum casing protects the battery from bumps, shakes and other impact abuse, and the battery looks well built. Two USB charging ports and the micro USB recharging port live on one side of the battery along with a LED indicator that displays the exact percentage of power the battery has left. The battery is easy to use: just plug in your devices and it'll automatically start charging them. To check the battery level, shake the battery to turn on the LED display. The Vinsic comes in four solid colors that should fit in with most of the device colors on the market.

The Vinsic Alien 20,000mAh Ultra-slim Power Bank has high capacity LG Lithium-Polymer battery. The 20,000mAh Power Bank can charge two devices simultaneously via one USB outputting at 2.1A and aother at 1A. We tested it with several smartphones and tablets and found that it could provide several full charges for most phones, though speed of charging varied quite a lot. The Vinsic charges iPhone 6 faster than it charges any Samsung and LG devices, for example. In our tests, the Vinsic filled up the iPhone 6's battery 6.5 times and it took less than 2 hours to charge the iPhone 6's battery from empty to full. The Vinsic filled up the Samsung Galaxy S6's battery 6.2 times but it took surprising nearly 6 hours to charge the phone from empty to full even when using the 2.1A port. The beefy battery can charge the iPad Air 2 at least 2.2 times which is a feat very few portable batteries have achieved.

The Vinsic Alien 20,000mAh Ultra-slim Power Bank offers modern battery safety features including over charge protection, over voltage, over discharge, over current and short circuit protection. The large battery capacity means it takes a long time, about 12 hours, to recharge. So be sure to recharge it before your trip. The battery has an excellent standby time.

With an iPad mini


The Vinsic Alien 20,000mAh Ultra-slim Power Bank is one of the most powerful portable batteries we've seen. It's slim so it should fit in your backpack or laptop bag easily. It's not light at 1.2 pounds, but if you need enough power to fill up your phone 6 times or more, it's a fair trade-off. The battery has high quality cells and important safety features. It can charge two devices at the same time, though it doesn't support power through, which means you can't charge your device while the battery is recharging. For tablet users who've been searching for something that works more than just topping off their tablet's battery, the Vinsic is certainly powerful enough for the job. It's a great choice for iPhone and iPad users as the battery is designed to fast charge these devices. It does take very long time to charge non-Apple devices however. We like the color options and the sturdy build, and even more attractive, the affordable price.
