Introduction

The Olsenmark OMPB1820 10000mAh power bank promises quick charging and the ability to power multiple devices simultaneously. After putting it through its paces over several weeks, I’m ready to share my honest assessment. Does this budget-friendly option deliver on its promises, or are there hidden drawbacks?

Features

The OMPB1820 boasts a number of features designed for convenience and efficiency. It features a 10000mAh Li-ion battery, dual USB output ports, pass-through charging (allowing you to charge the power bank and your devices simultaneously), and a power indicator light to show remaining charge. The compact size is also a significant advantage.

Performance

In my testing, the Olsenmark OMPB1820 performed admirably. Charging speed was consistently fast, though not quite as rapid as some higher-end power banks I’ve reviewed. Charging two devices at once did slightly reduce the charging speed of each, but this is expected. The pass-through charging feature worked flawlessly, allowing me to keep my phone topped up while the power bank itself recharged. The battery life met expectations, providing roughly three full charges for my iPhone before needing a recharge itself. The build quality feels solid for its price point, and the power indicator light is a useful feature.

However, there were a couple of minor downsides. The power bank does get slightly warm during prolonged use, which is a common issue with many power banks in this capacity range. Also, the supplied cable felt slightly flimsy, which might require replacing it over time.

Pros & Cons

• Pros: Dual USB ports, pass-through charging, compact size, good battery life, affordable price, reliable performance.
• Cons: Gets slightly warm during use, included cable feels a little flimsy.

Final Verdict

The Olsenmark OMPB1820 power bank offers excellent value for money. While it might not compete with top-tier models in terms of charging speed or build quality, it reliably delivers on its core functions and provides a convenient and affordable way to keep your devices powered up on the go. For occasional use or as a backup power source, it’s a solid choice. I would recommend this power bank to anyone looking for a practical and budget-friendly option.
