Top Picks
Anker 45W USB-C Charger Block (Ace Series)
Fast Charger Block
Okay, let’s start with something deceptively simple: a charger. I know, I know—nobody gets excited about chargers. But trust me, the Anker 45W charger is one of those most useful electronic gadgets that you only appreciate once you’ve used it.
This thing is fast. Like, absurdly fast for the price. Anker designed it specifically with Samsung’s Super Fast Charging 2.0 in mind, which means it can charge a Galaxy S23 Ultra in under an hour. Users repeatedly mention how this little cube “saved my mornings” because they could plug their phone in during breakfast and walk out with 100%.
And the size? Surprisingly tiny. It’s about 30% smaller than most 45W bricks—plus the foldable plug makes it a travel essential. I’ve seen countless reviewers say they carry it everywhere.
Another thing I love? It uses GaN technology. In case you haven’t fallen down that rabbit hole yet, GaN chargers produce less heat and deliver more efficient power. Basically: smaller, cooler, safer.
And speaking of safety—Anker added ten (yes, ten) safety features: temperature control, short-circuit protection, high-voltage regulation…the whole works. For a charger under $20, that’s just wild.
The only downside? The 5A cable needed for SFC 2.0 isn’t included. But honestly, that’s pretty standard.
If you’re building a kit of useful tech gadgets that make daily life easier, this one is a no-brainer.
Pros
- Charges Samsung phones ridiculously fast
- Compact foldable design makes it great for travel
- Built with GaN—cooler and more efficient
- Strong safety protections
- Works with iPhone, Pixel, iPad, and more
Cons
- Cable not included
- Needs a 5A cable for true Samsung SFC 2.0
Best For:
Anyone with a modern Samsung phone or anyone who needs a fast, reliable, travel-friendly charger.
Tile by Life360 Mate – Bluetooth Tracker & Key Finder
Smart Tracker
Now let’s talk about something everyone should own in 2025—even though many people still don’t: a Bluetooth tracker.
If you’ve ever lost your keys, bag, water bottle, or (and I say this lovingly) your entire peace of mind, the Tile Mate will change your life. It genuinely falls into the category of most useful electronic gadgets, especially if you’re forgetful like me.
The Tile Mate is like having a tiny superhero attached to your stuff. Lose your keys? You can make the Tile ring. Misplace your phone? Press the Tile button to make your phone ring—even if it’s on silent. Users absolutely love that feature.
This newest version also integrates with Life360, which is kind of a big deal. Life360 already helps families track each other’s locations; now you can add your belongings to the same map. Your people + your stuff = everything in one place.
One surprising feature? SOS alerts. If you’re in an unsafe situation, you can secretly trigger an SOS that notifies your family. It’s subtle, thoughtful, and honestly something I didn’t expect in a little $20 tracker.
Battery life lasts about a year. Range is strong enough for most homes and small offices. And the app? Clean, easy, and not overly pushy.
If you’re building a collection of cool gadgets for everyday use, this one deserves a permanent spot.
Pros
- Rings your keys/items when lost
- Can ring your phone even if silent
- Works with iOS and Android
- SOS alert feature for emergencies
- Integrates with Life360
- Lightweight and discreet
Cons
- Battery eventually needs replacing
- Works best within Bluetooth range
Best For:
Forgetful people, frequent travelers, parents, and anyone who loves peace of mind
Anker USB-C 20W Nano Pro Charger
Compact Fast Charger
If you’re an iPhone user, this is easily one of the must-have tech gadgets under $20 for 2025. The Anker Nano Pro is tiny, cute (yes, chargers can be cute), and surprisingly powerful.
Anker built this one specifically with iPhones in mind. It charges an iPhone to 50% in about 25 minutes—which is three times faster than those old 5W bricks Apple used to include in the box.
One thing reviewers consistently applaud? Heat management. Anker added something called ActiveShield, which sounds like a superhero suit but actually means real-time temperature monitoring and power tuning. Your phone stays safe, and your charger doesn’t overcook.
And because people like their gadgets to match their personalities, it comes in multiple colors. Small touch, but it matters.
Common feedback from users mentions how great this charger is for traveling, bedside tables, and work bags. People appreciate that it doesn’t block other outlets due to its tiny size.
Of course, like most chargers, the cable isn’t included. But still—at this price, it’s a steal.
Pros
- Excellent for iPhone fast charging
- Tiny, lightweight, and stylish
- Strong temperature control
- Multi-color options
- Very reliable Anker build quality
Cons
- No cable included
- Best optimized for iPhones (still works with others though)
Best For:
iPhone users who want faster charging without spending $30+
Amazon Basics 20W USB-C Wall Charger (PD)
Fast Charger
Amazon Basics might not have the “cool factor” of Anker or Apple, but man—do they deliver value. This is one of those budget friendly gadgets 2025 that punches way above its price.
If you need a reliable backup charger for home, office, or travel, this 20W PD charger is perfect. Users mention again and again that it “just works.” And honestly? That’s exactly what you want from a charger.
It supports fast charging for iPhones, iPads, Android phones, AirPods, and tons of accessories. The plug folds in, making it surprisingly travel-friendly. And for under $15, you get overheat protection, short-circuit protection, overcurrent protection, and basically every safety feature you’d expect from a good charger.
One thing to note:
It does not support Samsung’s PPS charging. So if you have a newer Samsung device and want ultra-fast charging, this isn’t the one. But for everything else, it’s terrific.
People love using these as backup chargers in bedrooms, kitchens, offices, and travel bags. It’s the definition of a “buy it once, use it forever” item.
Pros
- Very affordable
- Foldable plug
- Broad device compatibility
- Strong safety protections
- Reliable performance
Cons
- No PPS support
- Slightly bulkier than the Anker Nano
Best For:
Anyone needing a cheap, reliable secondary charger for everyday use.
Apple 20W USB-C Compact Power Adapter
Compact Wall Charger
And finally, the Apple classic. You’ve probably seen this charger more times than you can count—but don’t underestimate it. It’s one of the most useful electronic gadgets for Apple users, and for good reason.
Apple’s 20W charger is designed for efficiency, stability, and predictable performance. No surprises, no weird heating, no “does this work with my device?” confusion. You plug it in, and it charges your iPhone or iPad exactly as Apple intended.
Apple claims a 50% charge in around 30 minutes for the latest iPhones, and most users say that’s accurate. It’s not as feature-rich as Anker’s chargers, but it’s incredibly consistent.
The size is compact, the build quality is premium, and compatibility spans across practically all Apple devices plus most USB-C gadgets.
But the obvious drawback:
Apple doesn’t include the cable. And yes, it’s more expensive than similar chargers. But if you like original accessories, this is the safe bet.
Pros
- Accurate fast charging for iPhones
- Best compatibility with Apple devices
- Compact and durable
- Very stable, safe performance
Cons
- Cable not included
- Slightly pricier than alternatives
