Amazon is running a 1-day sale on PCs and accessories including storage, mice, monitors, and more.

You can score some pretty good savings in Amazon’s sale… but I think the best bang for the buck on a PC accessory today is Newegg’s ZeroLemon JuiceBox deal.

The JuiceBox is a USB power bank that you can use to charge phones, tablets, or other gadgets on the go. But this model also supports 45 watt USB-C power delivery, which means that you can use it to charge many modern laptops.

With a current list price of $50, it’s one of the cheapest battery packs that can power a laptop. But right now Newegg is selling the ZeroLemon JuiceBox for just $30, which matches the best price I’ve ever seen for this battery.

In fact, last time the price dropped this low, I picked one up for myself and I’ve been pretty happy with the purchase. While the 13 ounce JuiceBox isn’t exactly the smallest portable battery on the market, it effectively doubles the battery life of my HP Spectre x360 laptop.

Note that the JuiceBox does not come with a USB-C cable, so if your laptop came with a one-piece charger, you may need to buy a charging cable. But a cheap USB 2.0 cable will work just fine since you just need power delivery, not data transfer.

I picked up a braided 3.3 foot cable for $8 to use with my JuiceBox.

Here are some of the day’s best deals.
