Cool, you are right. Power sources are really in demand today, especially those who really needed a power. Such as

• SmartPhones
• Portable Speakers
• Emergency Use cases

However, we cannot say it is the most 'lightest' portable power station, which we already have an ordinary power bank. I think because it is called portable because you may be able to bring it with you, the great thing about this product are the following

• An AC outlet for your Computer (its like a UPS now lol)
• Cigar Socket
• LED Lighting
• Solar Input for availability of recharging the batteries

From the price, I think the price is pretty reasonable for a portable big powerbank lol. Nice

P.S.: Cant vote it, its very valuable.
