The Primus Eta Solo, introduced in late 2010, is the newest member of their expanding line of fuel efficient and wind resistant heat exchanger stoves. It’s obviously targeted at the Jetboil PCS because of its similar design and size. The burner is in fact identical to the PCS because Jetboil initially obtained their burners from Primus. A few differences are: the Eta Solo’s pot capacity (0.9 L) is slightly smaller, its robust QuickClick locking mechanism holds the pot securely to the burner, the cozy is made of heat-resistant fabric rather than neoprene, there is no temperature indicating strip on the cozy, there is no cap/measuring cup on the bottom of the pot, and Primus includes both a pot support and a hanging system.
In contrast to the locking mechanism on Jetboil systems, Primus’ QuickClick locking mechanism is much more secure, especially if you plan to hang the stove using the included hanging system.
With a measured total weight of 13.7 ounces (388 g), the Eta Solo is 1.2 ounces (34 g) lighter than the Jetboil PCS and an ounce (28 g) lighter than the Flash. But it’s not lightweight; the weight conundrum is still there: we like its convenience and efficiency, but we are reluctant to backpack this much weight.
The 0.9 L cook pot on the Eta Solo will cook in-pot for one or two hikers. For more cooking capacity, Primus does not offer larger heat exchanger accessory pots that attach to the burner base. But they do include pot supports for using the burner with a conventional cook pot or heat exchanger pots designed to fit over a conventional canister fuel stove. The conversion consists of three individual pot supports that slip into holes on the burner, plus a separate plate around the burner to prevent deflected heat from overheating the canister. The Primus pot support system is not as elegant as the one Jetboil supplies, and the individual supports will fall out if the burner is tilted.
In our performance tests, the Eta Solo is in the middle of the pack: a slower heating rate, very good fuel efficiency, very good wind resistance, poor cold resistance, and excellent burner control. Compared to the Jetboil PCS (our benchmark for integrated stoves), the Eta Solo is slightly lighter, has a similar heating rate, slightly lower fuel efficiency, similar wind and cold resistance, lower versatility (larger heat exchanger pots to fit this stove are not available), and similar burner control. Overall, its performance and utility are approximately the same.
The main strengths of the Eta Solo are its sturdy construction, fuel efficiency (almost as good as the Jetboil stoves), excellent burner control, better locking mechanism, and the inclusion of a hanging system. However, it lacks the performance of the next gen Jetboil Sol systems.
