I remember the days when a power bank was the size of a house brick and would get you about 30% charge, thankfully now these babies are getting smaller and more powerful. The P63-E1 from Iniu has a 25,000 mAh capacity and 100 W USB‑C PD output/input, it’s like carrying a small generator in your bag but fits comfortably alongside your devices.
This model is part of INIU’s “Cougar” line, designed to deliver high-speed performance without unnecessary bulk. Weighing in at around 392g and measuring 11 × 7 × 3.6 cm, it’s noticeably smaller and lighter than most power banks in its class. Making a great choice for travel, its airline-friendly and stashing easily in daypacks or laptop bags.
When using one USB-C port it will deliver 100 W, enough to fast-charge a MacBook Pro, laptop, Steam Deck, or smartphone at top speed, like a Samsung S24 Ultra hitting 75% in about 30 minutes. And if you’re topping up two devices, you’re still getting a whopping 110 W total output.
The TinyCell and HyperStack tech has enable this INIU to shrink down without sacrificing safety or capacity. It is worth noting that also its small, its quite fat (can power banks be fat?) and heavy so it’s not ideal for slipping into your pocket. There are two USB‑C ports and a USB‑A port for charging three devices simultaneously. A handy digital LED display shows you how much juice you have left in % instead of random light dots. It comes with a short built-in USB‑C cable and a travel pouch.
The INIU P63‑E1 is a compact powerhouse for tech-heavy travellers and professionals. With true 100 W charging, big capacity, smart size, and solid efficiency, it will comfortably keep your tech going until you are back near a mains plug. RRP £75.99
