Best praise vs top criticism for Jackery Explorer 300

Best Praise

+8 pts

“I have a 300 Explorer and can confirm they are solid. Used on multiple camping trips as well as a couple power outages. Can recharge from 20%-100% with decent sunlight in around 4 hours. Nice and portable, worth it imo. My unit is around 3 years old and running good as new.”

Top Criticism

+5 pts

“Good, since, since the Jackery is needed. Note, though, that the Jackery 300 is relatively low capacity. It'll only run a TV and router for (depending on the size of the TV) 2-3 hours.”

“Wife and I each have one of [THESE](https://www.anker.com/products/a1695-anker-power-bank-25000mah-165w?variant=44320657997974&ref=power-banks) from Anker (best battery backup I've ever used) and then [THIS](https://www.ecoflow.com/us/river-pro-portable-power-station) big boy from EcoFlow with a couple fold out solar panels. Done us great through multiple trips and power outages. Pretty much my perfect setup, not sure what I could improve if I wanted to beyond more solar for faster charging, maybe another big battery unit (they can daisy chain) but I haven't ran the one I've got dead yet so it's clearly not pressing. We also have [THIS](https://www.bougerv.com/products/crpro30-vip-30-quart-portable-fridge) electric cooler that can plug in or use a 9h battery for camping/travelling/power outages. VERY happy with it's first road trip from Seattle to Vegas and back, when we got home with covid we just plugged it in and our leftovers were still 31f a week later when we felt good enough to unpack.”
