Power Management Deals

Handy for electronics hobbyists or DIY power supply projects where you need to step up a DC voltage to a higher level, like powering 12V devices from a 5V source. The XL6009 chip handles up to 4A output, which gives it more headroom than the commonly used MT3608-based modules. Buy Now at Newegg

Handy for electronics hobbyists or anyone building a bench setup who needs to power multiple circuits at different voltages from a single source — the LM2596 chipset is a well-regarded buck converter, so you're getting reliable step-down regulation without building the circuitry yourself.

Handy for DIY electronics projects where you need to power a 12V component directly from a standard AC outlet without a bulky external adapter. Buy Now at Newegg

Useful for anyone running 12V car accessories or CB radios from a standard wall outlet, since it converts household AC power to the 12V DC that most automotive electronics require. Buy Now at Newegg

Bench power supply units at this price point usually top out around 300W to 400W, so the 600W capacity here gives you more headroom for power-hungry projects without stepping up to a much more expensive unit. A solid option for electronics hobbyists, engineers, or repair technicians who need adjustable voltage and current output on the workbench. Buy Now at Newegg

Useful for anyone running 12V car accessories or CB radios from a standard wall outlet, since it converts household AC power to the 12V DC that most automotive electronics require. Buy Now at Newegg

A tower-style surge protector works well for desks or entertainment centers where you need to power multiple devices in a tight space, and the 10-foot cord gives you more reach than the standard 6-foot options. At $23, that's about $9 off the $32 list price. Buy Now at Walmart

A tower-style surge protector works well at a desk, nightstand, or entertainment center where you need to charge multiple devices at once without fighting for outlets, and this one adds 6 USB ports on top of the 12 AC outlets. At $24, that's $8 off the $32 list price. Buy Now at Walmart

Useful for electronics hobbyists, engineers, or anyone building or repairing circuits that need to convert AC power to a stable DC output. Buy Now at Newegg

A tower-style power strip works well at a desk or entertainment center where you need to run multiple devices without fighting for wall outlets, and this one adds 4 USB ports for charging cables that don't need a brick. At $21, that's about $7 off the $28 list price. Buy Now at Walmart

Handy to have around if you do any DIY electronics work involving USB-C PD negotiation, since these modules let you pull a specific voltage from a PD charger without needing a full microcontroller setup. Buying a 10-pack keeps the per-unit cost low, which makes sense if you're building multiple projects or just want spares on hand. Buy Now at Newegg

Useful for anyone traveling internationally who needs to charge devices across different outlet types, since it consolidates multiple plug configurations into one compact unit rather than packing country-specific adapters for each destination. Buy Now at Newegg

A bench staple for electronics hobbyists and DIYers, this adjustable buck converter lets you step down a DC voltage to whatever level your project needs, with enough output capacity to handle most small motors, microcontrollers, and LED strips. Buy Now at Newegg

A single-outlet surge protector is useful anywhere you need to add basic spike protection to one device without running a full power strip, and this one is currently $2 off the list price. Buy Now at Walmart

Handy for DIY electronics projects where you need to step up voltage from a single lithium cell to USB-level power, such as building a portable charger or powering 5V devices from a 3.7V LiPo battery. Buy Now at Newegg

A buck-boost converter handles both stepping voltage up and stepping it down, which makes this useful for electronics projects where your input voltage might fluctuate above or below your target output. The 4-pack gives you extras to work with across multiple builds without paying for individual units each time. Buy Now at Newegg

Replacing aging UPS batteries in bulk is where this 8-pack earns its place, since buying individually tends to cost significantly more and most mid-range UPS units take 7Ah 12V sealed lead-acid batteries as their standard replacement spec. Buy Now at Home Depot

A 3-sided design means outlets face three directions, which cuts down on adapter and cable crowding at a busy desk or entertainment center. At $13, that's $2 off the list price. Buy Now at Walmart

Replacing the internal battery in a UPS like the CyberPower CP1500AVRLCD is the most cost-effective way to extend its life rather than buying a whole new unit, and buying a 10-pack brings the per-unit cost down significantly if you're maintaining multiple systems or stocking spares.
