Any self-respecting tech enthusiast knows you can never have too many smartphone charging accessories, so even if you don’t really need yet another power bank, power brick, versatile charging station, or car charger right now, you shouldn’t ignore Amazon’s latest one-day-only sale on RAVPower mobile peripherals.

Believe it or not, that’s actually the smallest power bank discounted today on Amazon, with 22,000, 26,800, and 32,000mAh options available at anywhere between $8.50 and $20.50 off their list prices, equating to markdowns ranging from 25 to 30 percent. Obviously, these are all very similar products (and they have similarly stellar customer ratings), although the three larger variants come with three USB charging ports each, while the smallest and most affordable option can only juice up two smartphones at once. 

None of the four power banks on sale today come with Qualcomm Quick Charge support, so if you’re interested in speed above portability, you’ll have to go for the 45W RAVPower USB-C wall charger fetching $9 less than usual, a 4-port car charger with a total output of 54 watts available at a 25 percent discount, and/or a 60W 6-port desktop charging station marked down by $9.50. 

Last but certainly not least as far as iPhone users are concerned, Amazon also has a 6-feet MFi-certified USB-C to Lightning RAVPower cable up for grabs at a $4, or 25 percent, discount at the time of this writing.
