Rivacase VA1091 varavirtalähde 25800 mAh 100W musta

The Rivacase VA1091 stands out with its 100W total output, enough to charge a laptop while topping up a phone and tablet simultaneously. Its 25800 mAh Li-Po cell holds 95.46 Wh, comfortably under the 100 Wh airline carry-on limit, making it a practical travel companion.

Highlights

• 25800 mAh capacity (95.46 Wh) charges a flagship phone up to five times
• 100W USB-C Power Delivery output supports laptops, tablets, and fast-charge phones
• Three output ports: two USB-C (100W + 20W) and one USB-A (22.5W Quick Charge)
• Recharges in approximately 2.5 hours with a 60W PD charger
• Comprehensive circuit protection guards against overcharge, over-discharge, over-current, over-voltage, short-circuit, and overheating

In daily use

The VA1091's 100W USB-C port delivers 20V/5A for high-power devices like Ultrabooks, while the second USB-C and USB-A ports handle accessories at 20W and 22.5W respectively. When all three ports are used together, total output is capped at 100W, so a laptop will still charge, just at a reduced rate. The black housing is understated enough for a professional bag, and the LED indicator shows remaining capacity at a glance.
