Anker Detachable Battery (New) for Portable Cooler

I bought this while Anker had a special on with the Everfrost 40 at $549.99 and you can add an extra battery for $99. This was a really good deal. It essentially is a portable power pack. 299wh for $99 is a really nice deal. Other small 250-300wh powerbanks/power stations are $250-300. Buying a lithium battery with 299wh capacity and building a powerbank yourself is still going to cost more than buying this at $99 so it was too good of a deal to pass
So far, it is working great. For long trips, it is good to have an extra battery for longer trips where you can swap and charge the other off a solar panel.
Sometimes the weather will not cooperate and solar panels are out. An extra battery is always a good thing to have.
Great product
Great battery, was fully charged when arrived, ran ever frost 53L for an hour off of it, charged quickly…like the c and usb ports, can be used as a giant back-up battery for laptops and cellphones
Love the battery use it all the time
