Ah, the modern world. Where our phones are our lifelines, our workstations, and our entertainment hubs. We don’t just use our smartphones to text a few friends or check the weather anymore. Oh no, my friend, we use them for everything from video calls to taking photos that make us look like a Bollywood star. But in this digitally dependent world, there’s one universal truth: if your phone dies, you feel like your entire existence has come to a screeching halt.
That’s why the portable power bank has become the unsung hero of the 21st century. We’ve all been there—running around the city like a headless chicken, frantically searching for an outlet, praying to the tech gods that your phone won’t give up on you mid-call with your boss, or worse, during the grand finale of your Netflix binge.
As a 42-year-old Sigma man (yes, I’ve earned that badge), I’ve seen it all. And trust me, having a reliable portable power bank is a game-changer. Let me walk you through the Top 5 Portable Power Banks you should have in 2025 to ensure you never face the dreaded “low battery” warning again. Ready? Let’s dive in.
1. Anker PowerCore 20100mAh – The King of Capacity
You’ve probably heard of Anker, and if you haven’t, well, you’re living under a rock, my friend. Anker is the gold standard when it comes to power banks, and their PowerCore 20100mAh is a true beast in the game.
Now, let me paint a picture for you. Imagine you’re at a family wedding in Goa (because, let’s face it, you’re probably going to one in 2025). You’re clicking photos, uploading them to Instagram, replying to 17 WhatsApp groups (because Indian families just love them), and, oh, let’s not forget, checking your work emails (because apparently, you can never fully escape work).
Here’s the thing—your phone’s battery is plummeting faster than your patience at the buffet queue. Enter the Anker PowerCore 20100mAh. With its massive 20100mAh capacity, it can charge your phone 4-5 times in one go. That’s right—your phone will be as good as new while you’re living your best life at the wedding. It has two USB-A ports, so you can charge multiple devices at the same time. Plus, it comes with VoltageBoost and PowerIQ technology, ensuring your devices get charged quickly without any funny business.
The PowerCore is built like a brick, but unlike a brick, it’s not going to ruin your back. It’s surprisingly lightweight, and its premium matte finish gives it a classy feel.
Verdict: For the Sigma man who values reliability and power, this one is a must-have. You’ll never have to worry about your phone dying while you’re mastering your dance moves at that wedding.
2. Xiaomi Mi Power Bank 3i 20000mAh – The Value Champion
Now, we all know how much Indians love value for money (and why shouldn’t we?). Xiaomi’s Mi Power Bank 3i 20000mAh is the epitome of the term “paisa vasool.” For just a fraction of the price of some of its competitors, Xiaomi delivers a power-packed product.
Let me tell you about the time I used this baby during a trip to Bangalore. My phone had the audacity to die in the middle of a client meeting (I mean, seriously, does the universe just hate me sometimes?). Thankfully, I pulled out the Mi Power Bank 3i, and within no time, my phone was back in action. The 20000mAh capacity is more than enough to charge your phone 3-4 times. It also supports 18W fast charging, so no more sitting around waiting for your phone to juice up.
It’s sleek, compact, and as reliable as your mom’s cooking—and that’s saying something. The build quality is solid, and it even has a dual USB output, so you can charge two devices simultaneously. What more could you ask for?
Verdict: If you’re a tech-savvy Sigma man on a budget who likes to stay charged without burning a hole in your wallet, this is the one for you. Plus, Xiaomi’s customer service in India is top-notch—so you’re covered if anything goes wrong.
3. Realme 30W Dart Charge Power Bank 10000mAh – The Speedster
Alright, I get it. Some of you can’t stand waiting for a slow charge. You’re impatient. You’ve got places to be, people to impress, and probably some serious Netflix to catch up on. The Realme 30W Dart Charge Power Bank 10000mAh is the answer to your charging woes.

I tested this power bank on a trip to Pune (because I was feeling fancy, okay?), and let me tell you, it didn’t disappoint. The 10000mAh capacity is good enough for a 1.5-2 times charge, but the 30W Dart Charge made me feel like I had a charger straight out of a sci-fi movie.
The design is sleek and modern, and it fits easily in your pocket. Plus, it has multi-layered protection, so you won’t be worrying about overheating or short-circuiting (which, let’s be honest, we’ve all done at some point).
Verdict: If you’re someone who values speed and performance, this is the portable power bank for you. It’s fast, reliable, and won’t leave you stranded with a dead phone.
4. iMuto 20000mAh – The Heavyweight Champion

I remember using this during a long, endless road trip to Rajasthan. The moment I pulled it out, my friends looked at me like I was a tech wizard. Why? Because with its huge 20000mAh capacity, I was able to charge my phone, my friend’s phone, and even the car’s Bluetooth speaker.
