This Jackery Explorer 240-Watt Portable Power Station, originally listed at $299.99, is on sale for $219.99 at Jackery via Amazon. It drops even further to $199.99 when you click the on-site coupon. Plus shipping is free. That's the best price we could find by $20. It can recharge a typical cellphone 24 times. You can pair this device with these on-sale Jackery solar panels to keep it charged on longer trips. Editor's Note: I have this power station and use it to power various devices on multi-week camping trips.
