Baseus’ official Amazon storefront is extending the savings on its 4-Port 145W 20,800mAh Power Bank for $44.45 shipped, after using the promo code RVDNG3WN at checkout. Normally, you’d be spending $90 for this model at full price, which we saw dropped to this same rate for Prime Day last week, with the deal continuing here today. You can pick it up while things last with a combined 51% markdown that saves you $46 in total at the best price we have tracked.

A great option for folks not wanting to spend higher rates for equally sizeable power banks, this Baseus backup power solution comes boasting a 20,800mAh battery to cover your smartphones, laptops, and much more. It sports two USB-C ports and two USB-A ports in all, topping off your devices with up to 145W output, with up to 100W speeds for a single device connection. You’ll be able to fast charge the latest iPhone at 45W or utilize the 100W output for your MacBook, for example. There’s also an onboard display that gives you all the real-time charging data you could want at a glance.

While it’s no longer down at $75, you can still grab Belkin’s BoostCharge Pro 2-in-1 MagSafe Charging Dock at $80 while the savings last, or find other devices for keeping your personal devices running collected together in our smartphone accessories hub here.
