What got old really quick while camping was maintaining an ice cooler and the gf wasn’t going to put up with soggy, floating food. She takes her food seriously!
So our first “overland accessories” purchases were:
- an Arb 63QT from Amazon, $1,005.11 & free shipping
- An Arb transit insulator bag from Amazon, $133.99 & free shipping
Since I still needed to go to the office everyday, I needed a power source that I could leave behind with the fridge at the campsite. That meant a dual-battery setup wouldn’t help in this situation, so after some research I nabbed a pair of Aspect Solar Energy Bars.
At the time, I paid $507.83 each / $1,015.66 for the pair. They are a 294 watt hour LifePO4 lithium battery. At first I was looking at the Yeti Goal Zero batteries but they didn’t offer lithium options at the time, and I couldn’t imagine lugging around two Goal Zeros running AGM batteries.
As of right now 6/9/17 you can find the Energybars on Amazon for really cheap. It seems the company went out of business, with many people complaining of getting used items from their Amazon purchase, their warranty not being honored, or battery meter being faulty.
Luckily I received brand new ones at the time and it doesn’t seem that my meter is faulty, though I don’t pay too much attention to it.
Charging Performance - I’m really impressed with how fast they charge from the AC adapter. Website claimed 3 hours but I found sometimes it recharged a completely dead battery in less than 2 hours, from the 15V/8A ‘quickcharge’ socket.
Two hours seems fast when I was charging it at the office. Two hours seems like an eternity when I was always trying to charge it in a cramped coffee shop on weekends when not at the office. Why?
Because charging performance from 12v is dreadfully slow. I’ve started whole day trips from a dead battery and it still hasn’t fully charged with a full day of driving. The 12v adapter works best as a trickle charger to keep the battery topped off.
This is how I’ve been using it up to now:
12v adapter from cig outlet to trickle charge a fully charged battery
Fridge plugged into battery
In this way, the battery stays at 100%.
Runtime Performance - Unplugged, the battery consistently lasted over 24 hours running just the ARB fridge. Fridge was kept at the campsite full time, inside the food lock box. This was throughout the summer, so ambient temps at the campsite ranged anywhere from 50s in the morning to 80s in the late afternoon. This worked great as I would charge one at work and just swap it out everyday when I got back to camp.
So, a price recap:
ARB 63QT: 1,005.11
ARB transit bag: 133.99
(2) EnergyBars: 1,015.66
Total fridge setup: $2,154.76
Overall, I am happy with my purchase but wouldn’t recommend this exact product to others as the company has gone out of business so there would be no honoring of any warranty.
Until I get back on the road full time, I’ve been keeping one at home and one in the truck as backup emergency power. Later on, will look at different ways to integrate them into the dual battery setup I’ve got on the truck now.
Does anyone know if there’s a way to use the Energybar to charge the truck battery in case of an emergency? I was thinking maybe the 12V/20A outlet? But I don’t know what kind of outlet that is or what goes in it..
