Been shopping "solar power stations" for a while and not ready for an expensive plunge. This one by Paxcess gets good reviews on Youtube and Amazon (4.5 out of 5). Great starter unit that can be recharged by included AC adapter, included DC plug adapter (cigarette lighter), or your own USB type C power delivery wall charger, or optional solar panels.
For newbies, they are referred to as "solar stations" when the can be recharged by solar panels.
Great for camping and travel or emergency power outages to recharge small devices like phones, tablets, small lights and fans, but not power intensive devices. Station can recharge USB & DC while it is being charged, but no AC while being charged.
A common cost estimate to purchase a power station is $1 per watt making this an amazing deal with the $40 off coupon code and no tax (70 cents per watt). Free shipping to USA, likely from China.
This item is available on Amazon with Prime delivery for $40 more.
