The Goal Zero Yeti 400 Solar Generator offers power to those looking for an off-the-grid getaway, or power for emergency uses, although it is most effective when fully charged by a power outlet, and topped-off using solar panels (sold separately). This generator is popular with people using CPAP machines while camping for a few days, and also has multiple ports for charging devices simultaneously. This does not have the capacity to power kitchen appliances, but for specific uses and portability this generator is a solid choice, although the battery may not last long enough to justify the price.
