As part of Amazon’s Deal of the Day promotion, you can grab various Anker charging accessories for anywhere from 25 to 45 percent off.

One highlight is the Anker PowerCore II 20000, a 20,000mAh portable battery that features two full-size USB ports. The battery charges over Micro-USB, but that’s tolerable when you’re only paying $39.88 for all that capacity.

Also of note is the Anker PowerWave 7.5, a wireless charging stand that charges recent Samsung Galaxy smartphones at 10W. If you happen to live in Apple’s walled garden, the PowerWave 7.5 charges your iPhone at 7.5W.

Even better, the PowerWave 7.5 includes a Quick Charge 3.0 wall charger. Its inclusion makes the PowerWave 7.5’s $34.95 price tag that much better.

That said, Anker offers much more than just a portable battery and wireless charging stand. Check out all of the Anker deals on Amazon at the links below. Keep in mind that the discounts will go away either by the end of the day or when a product is sold out, whichever comes first.
