With so many power bank options flooding the market, it’s easy to get overwhelmed—especially when deciding on battery capacity. Should you go for 5,000mAh, 10,000mAh, or a massive 20,000mAh model? Is bigger always better? And how do you know which one fits your lifestyle?
These are valid questions, particularly for users in Bangladesh who juggle busy commutes, frequent power outages, and the need for reliable mobile access. In this article, we’ll help you figure out how much power bank capacity you really need based on your usage, budget, and lifestyle.
Understanding mAh: What Does It Mean?
mAh stands for milliampere-hour—a unit that tells you how much energy a battery can store. The higher the mAh, the more charges it can provide before needing a recharge itself. For example, a 10,000mAh power bank can charge most smartphones about two times, while a 20,000mAh unit may deliver four or more full charges.
However, it’s not just about numbers. Some energy is lost during the charging process due to heat and conversion, so actual performance is slightly lower than the stated mAh.
Light Users: 5,000mAh to 10,000mAh
If you’re someone who uses your phone mainly for calls, messaging, and occasional browsing, a 5,000mAh to 10,000mAh power bank should be enough. These are compact, easy to carry, and affordable—making them a good fit for students, office workers, or elderly users.
They’re also ideal as backup chargers during short outings or emergencies.
Moderate to Heavy Users: 15,000mAh to 20,000mAh
For people who rely heavily on their smartphones for work, content consumption, social media, and video calls, larger capacity power banks make more sense. A Baseus Power Bank 20000mah offers multiple recharges for smartphones and even supports tablets, gaming devices, and wireless earbuds.
If you travel frequently or live in areas with unreliable electricity, having this much capacity ensures your devices stay powered all day. The added bonus? Many of these models support dual-device charging, so you can charge your phone and your smartwatch simultaneously.
Power Users and Tech Enthusiasts: Go Big or Go Home
If you’re a vlogger, gamer, or digital nomad carrying multiple gadgets, your power needs are significantly higher. A 20,000mAh model is often the minimum. Some even go for dual power banks to ensure uninterrupted access.
Look for features like USB-C PD, fast charging, LED displays, and rugged builds. The good news is that high-end models from brands like Baseus Power Bank deliver all of this at surprisingly reasonable prices in Bangladesh.
What Capacity Means for Your Budget
Of course, capacity affects price. Generally speaking, the power bank price in BD ranges like this:
- 5,000mAh – 10,000mAh: BDT 800 – 1,500
- 15,000mAh – 20,000mAh: BDT 1,800 – 3,200
- Premium, fast-charging models: BDT 3,500 and above
While it’s tempting to just buy the biggest one available, choosing a capacity that matches your needs will give you better value for money. Smaller models are easier to carry and charge quicker. Larger ones provide peace of mind for long days and trips.
