Regular power banks and battery packs are nice, but if you want something that can truly handle it all, the Anker SOLIX F3800 Power Station is the company’s best battery that is still considered portable. This thing is so powerful it can power whole homes, RVs, or charge your electric vehicle. It’s not cheap at $3,999, but right now, there’s a very nice deal that saves you a whole $1,300, bringing the price down to a more manageable $2,699.
