There’s a specific kind of panic that sets in when you realize you’ve packed your power bank but forgotten the charging cable. It’s a classic tech-lover's fail. Realme seems to be banking on that relatable frustration with its latest release in India: the Realme TechLife 45W 20,000mAh Power Bank.

Launched alongside the new Buds Clip, this brick isn't just about raw capacity; it’s about a design that actually considers how humans live in 2026. With a built-in Type-C cable and a 45W output, it’s a clear shot across the bow of the generic, slow-charging power banks that have dominated the market for far too long.

More Than Just a Basic Battery

What caught my eye here isn't just the 20,000mAh capacity—which, let's be honest, is the standard for anyone who travels—but the 45W fast charging. Most mid-range banks are still stuck in the 18W to 33W purgatory. Realme claims this will juice up an iPhone 16 over four times or a Realme 15 Pro twice.

But I think the real "killer app" is the 50% charge in just 26 minutes for compatible devices. In a world where we’re constantly running between meetings or flights, that half-hour window is usually all we get. The inclusion of a low-current mode for smartwatches and earbuds is a thoughtful touch, too. There’s nothing more annoying than a high-capacity bank that refuses to "see" your tiny earbuds because they don't draw enough power.

Aesthetics and Utility

Design-wise, Realme is leaning into that 3D-transparent shell look that’s been trendy lately. It looks more like a piece of gear and less like a boring office supply. Available in Obsidian Black, Glacier White, and Amber Yellow, it actually has some personality.

The built-in dual-sided USB-C cable handles both input and output. This means you can charge your phone with it and recharge the power bank itself without hunting for a spare cord. Weighing in at 359g, it has some heft, but considering it packs enough juice for a long-haul flight (and yes, it is airline compliant), that's a fair trade-off.

My Opinion: Is it Worth 30$?

If you're still using a 10,000mAh bank that takes five hours to charge your phone, this is a no-brainer. At ₹2,799 (30$), it’s positioned slightly higher than the budget alternatives, but you’re paying for the convenience of not carrying extra wires. I've personally lost enough cables to realize that a "cabled" power bank is basically an insurance policy against my own forgetfulness.
