Currently, AUKEY's 10,000mAh battery pack or portable charger, is available on Amazon for just $14.99 when you use the promo code AUKPBN51 at checkout, through May 2nd. That's $5 off of its normal price of $19.99, making it a pretty worthwhile purchase, especially if you are in need of a new battery pack.
This battery pack from AUKEY is a pretty slim one, and it still has a 10,000mAh capacity. This has enough capacity to charge your smartphone around 3 times or so, depending on the device's battery capacity. It's enough to charge your tablet as well, if needed. It also sports two USB-A ports for charging multiple devices simultaneously. However, it does charge via a micro USB port. There is no Quick Charge 3.0 support here, but AUKEY's own AiPower is here. This is adaptive charging technology which allows the battery pack to charge your device as quickly as it can without damaging your device, or setting it on fire.
The AUKEY 10,000mAh battery pack is eligible for Amazon Prime's free shipping. If you are not a member of Amazon Prime, you can sign up for a free 30-day trial and take advantage of unlimited two-day shipping as well as the many other perks that Amazon Prime includes.
