Did you pick up a new smartphone or tablet this Black Friday? If so, you may want to check out the deals that Amazon is running on some Anker products today as part of their Deal of the Day program.First up, the Anker Astro E1, a 5200mAh portable battery. That may not sound like much, but it's good for between 1.5 and 2 full charges of a typical smartphone at 2A speeds. For $11.99 (about $4 cheaper than usual), you can't argue too much with the small capacity, as the small form factor is part of this battery's appeal anyway.Looking for a larger battery? The Anker PowerCore 20100, which has an easily guessed 20,100mAh capacity, may be more up your alley. This thing, with its two 2.4A ports, can charge the average smartphone between 6 and 8 times. Its $27.99 price is around $12 cheaper than usual, which makes it great bang for the buck.If you'd rather have a quick charger, you may want to consider the poorly named "Anker Quick Charge 3.0 39W Dual USB Wall Charger, PowerPort Speed 2." This charger features two ports capable of Qualcomm Quick Charge 3.0 speeds, which will allow you to charge your shiny new smartphone as fast as humanly possible. The sale price of $19.99 is about $8 lower than usual.As of this article's publishing, these deals will expire in around 7 hours, so don't wait too long if you're interested.Source: Amazon
