Works like a champ

We use a Yeti 1000 already. This Yeti 3000 is great because it stores more energy. But the 3000 is also great because it comes with two AC adapters instead of one, so we can mulitplex the charging when using the wall. Also, the charge controller is an MPPT instead of the PWM on the Yeti 1000. Higher voltage input is possible with the MPPT.
ProsMPPT charge controller.
2 AC adapters for DC input from the wall
Sturdy wheels with extendable handle
A LOT of energy is stored in here.
ConsCannot charge DC from another Yeti. Charging from another Yeti is via the AC inverter output to DC input, which is inefficient. Some significant % of energy is lost as heat when doing this.
Instructions do not indicate that best battery life is achieved by not charging beyond 80% and not discharging below 20%, but I suspect that this is the case since the battery is lithium ion.
