A slow leak behind a shower wall or under a window can rot framing long before you see a stain. Klein's ET140 lets you check drywall, masonry, hardwood or softwood for hidden moisture without poking pin holes in it, because it reads through the surface with an electromagnetic field, up to about 3/4 inch deep. Lowe's has it for $39.98, ten dollars below its regular $49.98. You pick the material with a mode button, and a nine-bar LED scale on a high-contrast screen shows how wet it is, with hold, low-battery and auto-off features. It is rated to survive a 6.6-foot drop and comes with a 9V battery. Handy for home buyers, flippers, flooring installers and anyone drying out after a leak.

DeWALT 5" Random Orbit Sander Kit (DWE6421K) $64.89 at Amazon (30% Off)
Price: $64.89 at Amazon · Savings: About $29 under the $94 list price (30% off)
Shipping: Free shipping · Expires: No end date listed; Amazon prices change often
If you refinish furniture, build cabinets or prep trim for paint, a random orbit sander saves hours over a sanding block. Amazon has DeWALT's corded DWE6421K kit for $64.89 with free shipping, about 30% under its $94 list. A 3-amp motor drives the 5-inch pad at 12,000 orbits per minute, a separate counterweight cuts down on vibration, and the low body puts your hand closer to the work for better control. DeWALT also improved dust sealing on the switch and gave it a dust bag that locks on with one hand, and the port fits DeWALT's DWV010 and DWV012 dust extractors directly. Corded means no battery to run down halfway through a tabletop.

wegear 140W 4-Port GaN USB-C Laptop Charger $23.99 with Code at Amazon
Price: $23.99 with code HE25DHSO ($44.99 before code) at Amazon (Lenovo Product Marketplace) · Savings: $21 off with promo code HE25DHSO
Shipping: Free shipping · Expires: No end date listed; Slickdeals marks it as still available, but codes can be one-time use
One charger that can run a laptop, phone, tablet and earbuds at once cleans up a desk or a travel bag. This 140W wegear GaN charger has three USB-C ports (140W, 100W and 65W max) and one 22.5W USB-A port, and the top port uses PD 3.1 to push the full 140W, enough to fast-charge a 16-inch MacBook Pro. It is sold on Amazon by Lenovo's marketplace store for $44.99, and code HE25DHSO takes $21 off for $23.99 with free shipping, in black or silver. The plug folds flat, it is billed as 27% smaller than a typical 140W brick, and it has over-current, over-voltage, over-temperature and short-circuit protection. The listed max outputs apply when one port is used alone, so expect lower per-port wattage when you charge several devices at once.

Anker PowerExpand 8-in-1 USB-C Hub $40 at Amazon (26% Off)
Price: $40 at Amazon · Savings: About $14 under list price (26% off, per DealNews)
Shipping: Free shipping · Expires: No end date listed; DealNews shows the Amazon offer in stock
Thin laptops tend to ship with two USB-C ports and nothing else, which makes plugging into a desk setup a mess of dongles. Anker's PowerExpand 8-in-1 hub turns one USB-C port into two HDMI outputs, wired Ethernet, two USB-A ports and an SD and microSD card reader. Amazon has it for $40 with free shipping, which DealNews puts at about $14 (26%) under list. It is a good fit for a home office or hot desk where you want two monitors, a stable network connection and a keyboard and mouse running from a single plug. Two things to know: on a Mac both external monitors show the same image rather than extending the desktop, and no wall charger comes in the box.
