Portable chargers and external batteries are a staple for those of us who are on the move a lot, but most are not built for use in rough outdoor conditions. If you require a charger that is tough enough to be your companion in the great outdoors, or if you already own one but it isn’t quite suited for hitting the trail, then the rugged Unifun waterproof power bank may be what you need. For a short time, Amazon is offering this portable outdoor charger for just $13.50 when you enter the coupon code 7KYUNRJU at checkout.

The Unifun U821 power bank contains a 10,400mAh internal battery which offers enough juice for roughly five charges for most standard-sized phones or around three charges for larger models. The battery is paired with dual USB ports for charging two devices at the same time. Four LED lights on the side of the unit give you a quick visual indication of when it’s running low, and the device can be fully charged in under seven hours for several days’ worth of power on the go.

The U821’s shock-resistant housing and IP66 dustproof and waterproof rating make it ideal for camping, hiking, or any outdoor activity where a standard charger might not hold up. Its body is bright orange for easy visibility in case you drop it in tall grass, water, or other places where a dark-colored unit might be easily lost. The power bank also doubles as a high-powered LED flashlight which can provide six to eight days’ worth of light when the internal battery is fully charged.

The Unifun waterproof power bank normally costs $17, making it an affordable option for a rugged outdoor charger even at its regular price. You can now take $3.50 off with the checkout code 7KYUNRJU, bringing the price down to just $13.50 for a limited time.

LG just knocked $300 off this 16-inch lightweight laptop

lg ultrapc 17 review front angled

For those people who are constantly on the go, grabbing a thin and light laptop makes life a lot easier, especially since they tend to weigh a lot less while also having very capable performance. Unfortunately, that does come at a bit of an extra cost, so we're happy to see this deal from LG on the UltraPC laptop that knocks it down to just $700 from its usual price of $1,000. That's an excellent price for a laptop that can outperform competitors at the same price range, even with the discounted price.

Why you should buy the LG UltraPC laptop
This new version of the Ultra PC is a big upgrade on the previous LG UltraPC laptop and follows the same lineup of LG's very thin laptops like the LG Gram 17, so LG has quite a lot of experience in this market. That's pretty obvious by the fact that the UltraPC has a tiny 0.64-inch thickness, making it thinner than many books. It doesn't lose out on other features, though, and it still comes with a pretty substantial 16-inch screen that runs a modified FHD resolution of 1920 x 1200, which may be a bit low for such a nice laptop, but it's not a dealbreaker if it helps keep the price down. The keyboard is also great to use, and while the previous version of the UltraPC had a comically small touchpad, this new one is a lot more substantial and useful.

Windows 11 Home usually costs $139 — but it’s only $30 today

If you've recently bought yourself a new desktop or laptop, you're most likely using Windows 11 Home edition, which is still pretty good, but it does lock some features away that you can only get with the Pro edition. While they aren't completely necessary, they are nice to have, but the usual $200 cost of a Windows 11 Pro license means they aren't worth the cost. Luckily, there's a great deal from StackSocial that discounts Windows 11 Pro down to just $30, which constitutes a whopping 84% discount on the regular price. You better grab it quite too, because the sale is going to be ending soon.

Why you should buy Microsoft Windows 11 Pro
Most of the features that you'll find on Windows 11 Pro are targeted to, you guessed it, professionals, but that doesn't mean that you can't also take advantage of it. For example, while both versions of Windows 11 are pretty secure, Windows 11 Pro has extra security features. For example, the Pro version comes with Defender Application Guard, which is an additional level of security that protects your files even if your computer is stolen, and the BitLocker can directly lock your files so nobody can read them even if they can access them.
