The UGREEN 48000mAh 300W now costs 2,599 Kč with code ALZADNY40 instead of 3,999 Kč. Let’s see how it differs from common models and who it’s worth it for. CHCI POWERBANKU ZA 2 599 KČ Quick summary:✅ Makes sense if you want large capacity, fast power bank recharging (~1.5 h), and cells that last for years.⚠️ Consider that it weighs over 1.6 kg and the capacity is not enough for all-day laptop power.💡 For 2,599 Kč with code ALZADNY40, you get a quality power bank with a negligible complaint rate of 0.92%. How it differs from cheap power banks The main difference is LiFePO4 cells (lithium iron phosphate). Instead of the usual approximately 500 cycles in common power banks, they can handle up to 3,000 charges and still retain over 80% of their capacity – they are also safer and less prone to overheating. The second difference is speed: thanks to bidirectional PD 3.1, it recharges itself in about 1.5 hours (where other high-capacity banks might need a whole night) and can charge five devices simultaneously via 300 W distributed across five ports. You can see the status on the real-time display. The high quality is also confirmed by the low complaint rate. What to watch out for The price for the features is a weight of over 1.6 kg and larger dimensions. And let’s be honest about laptops: while 140 W input will charge a laptop, the 48000 mAh capacity won’t power it for days – consider it more as one to two extra laptop charges, whereas for phones, watches, and headphones, it’s a long-lasting power source. A minor point from reviews: the last percentage of its own charging takes longer, which is normal for batteries. If you are looking for a quality power bank for years to come that can handle all your small electronics and occasionally a laptop, it’s a great choice for 2,599 Kč. For everyday pocket carry, choose something smaller. CHCI UŠETŘIT 1 400 KČ When it comes to power banks, do you bet on long lifespan, or mainly on the lowest possible price?
