Great quality. Using it primarily to power the battery tender on my motorcycle in winter storage. Bought two so one would always be charged at home for power outages.

Power went out and the unit worked well to keep our fridge going. Easy to operate.

I bought this battery with the sole purpose of charging devices at camping festivals and it has done just that. I love that I can charge devices for myself and 1-2 others for 4 days straight before it runs out.

The Jackery was an amazing addition to our camping gear. At night we were able to run our fan and charge our phones. We could recharge our Jackery when we drove our van. Such an amazing product that helps you have charging power for your devices. I was so glad that we purchased this product. It is easy to use and easy to store as it is a smalll size and fairly lightweight. I give this product a 2 thumbs up.

SO far I have nothing but positive feedback on this power bank. Had my PJ welder hooked to it for 6 hours and still had plenty of charge left, its portable and I have already made my money back on it!

When/if your power goes out, this little (and very lightweight) Jackery 300 keeps the lights on. No shuffling around looking for a flashlight, etc. It's very easy to use, and its small size makes it easy to keep in any cabinet or closet.

I have been tinkering for some time pairing (much less wattage) LiFePo 12v10aH batteries with USB dash mounts, 12v SAE & lighter plugs paired with 150w inverters usually a mess in a tub of almost usable in non existent extreme situations. TIME FOR AN UPGRADE?My Refurbished grab bag chance came what I would call NEW but as the new price dropped the following week, that may explain that.Size wise? Well let's be honest there is very little the modern home or glamper is going to use it for that is cost effective or long duration even at 4x the price/capabilities. So price per watt and reasonable expectation wise at a size & weight not unreasonable to pack along, it is in a sweet spot.Primary perks for me were pass through charging & dual solar + USB-C charge capabilities. (WARNING you will need an off brand 12v capable USB-C solar output to utilize that feature off grid. It won't double the charge in itself but bumping a hand full of watts is priceless.The lame experiment (Duh, at much over cost of current grid electrical) can I charge a 36v 15aH (over 500aH but within specks @ ex: 42v 2a 120v ebike charger = 85aH & down inverter draw) with this AND a 100w panel on a SUNNY mid day?(Answer: You can but ONLY if you go off label with a FlexSolar 100w (w/USB-C 12v 60w dual mode capabilities. 800ish aH need is a lot to expect from a mere 280is aH device without a lot of solar help)Otherwise charging phones or running led lighting & smaller 120v devices for limited periods vs tub of wannabe spare parts for the expected 2x the cost and 2x the capacity at half the weight of the tub of loose stuff, it's a win win.Sure not as repairable as a tub of junk but "oops I forgot" wise it's priceless. Built in MPPT charger eliminates another pile of lesser stuff.Assuming you can believe what it is telling me, I have toyed with a lot of PWM and even MPPT loose charge controllers. THIS alone seems to maximize optimum & non optimal solar sunlight charging.Built in MPPT utilization on any panel was an unexpected bonus as well.Just be reasonable on what it can and can not run for how long. Portable with multiple features in a tiny footprint and reasonable price point is what it offered to ume. Dual (in our case solar simultaneous) charge capable is why we went with at least the 300 model here. Name recognition/reputation the other.
