Primus EtaPower EF Integrated Cooking System (Outdoor Retailer Summer Market 2006)

Hey, move over Jetboil and MSR, Primus is also coming to the table with an integrated system. Woo-hoo, the competition is heating up!

The third integrated canister fuel cooking system to hit the market soon is the Primus EtaPower EF. Primus takes a somewhat different approach to create an integrated canister fuel cooking system, and in several ways it's more versatile than systems from Jetboil and MSR.

The new Primus EtaPower EF integrated canister stove is a remote canister system, rather than a top mount system like the Jetboil and MSR.

Primus's system is fundamentally an adaptation of existing technology. The burner base holds a burner identical to the Primus Micron that has been throttled down to yield 7150 BTU/hr. It has a push buttom piezo igniter. The MSRP will be $110, which is a good value.

The system consists of a fuel line and valve connected to a remote fuel canister, a burner base with pot supports, a windshield, an aluminum pot with heat exchanger fins attached to the bottom, a lid that doubles as a frypan, and a carry case that doubles as a cozy. All of the aluminum components are black annodized to facilitate heat transfer.

The wide cookpot provided with the EtaPower EF stove has a 2.1 liter capacity and has heat exchanger fins attached to the bottom. According to Primus, the pot can be used with conventional stoves to increase efficiency.

The weight is 27.3 ounces for the whole package, including a pot grabber. Arrghh, you say? Actually, the weight is not as bad as seems because you can leave the carry case and pot grabber at home and save 8.7 ounces, making the weight comparable with the Jetboil and MSR systems. Having said that, the bottom line is none of these systems is truly lightweight.

The versatility in the Primus system is:

  • It is a remote canister system and has a pre-heat tube, so you can use it as a liquid feed system
  • The cookpot is 2.1 liters, larger than the MSR or Jetboil, and a 1.7 liter pot is available. Both pots are wide to facilitate heat transfer
  • The cookpot with attached heat exchanger fins can be used on other conventional stoves
  • You get both a cookpot and frypan for the same weight as the MSR or Jetboil systems

Primus claims that the EtaPower will boil 28 liters of water from a single 8-ounce fuel canister. For comparison, MSR claims their new Reactor Stove will boil 22 litres per canister. So, it looks like we have some good competition "heating up" here.

At this point, I know exactly what you're thinking - Backpacking Light needs to do an in-depth comparison of the three systems under controlled conditions and report on their comparative fuel efficiency and performance. We're on it, expect a full report in a few months.

Definitely want to try... on 08/12/2006 09:52:35 MDT Print View

there are a number of reasons why I think this one may be the one for me to buy...

This can likely be quickly and easily adapted to other burners... alcohol or esbit... of course the MSR might be able to do that as well...

This one looks like the verenable trangia 'system' upgraded with new material / tech... very nice...

Individual pot weights ? on 08/12/2006 16:05:02 MDT Print View

There's an interview with Yorkim Gramik from Primus about this new stove at
( look for The Outdoors Channel Magazine No 4 ).
Since the pots will be avalaible seperately, I wonder what their weight is and if these will have a normal lid or a frying pan? It certainly looks like an interesting option to improve efficiency without having to buy a complete new stove set up.

The during the interview Ryan did with the Primus guy he said that the 1.7L pot weighed 4.9 ounces.

I want to volunteer to put the Primus EtaPower setup on a diet if someone wants to send me one.

If anyone's the person for the job it's you, Bill. Your skills as an engineer and craftsman are a veritable force 'round these parts.

pot weight on 08/12/2006 17:18:31 MDT Print View

4,9 oz is quite good. I currently use an MSR Duralite 1,5 L which weights 5,6 oz. The new Primus pot would reduce weight ,increase volume (ok, that's not always positive) and more importingly increase efficiency. Well, how long do I have to weight till these are available?

I like the fact the this stove has a remove canister to allow the ability flip the canister and liquid feed the fuel.

Here's a link to the product sheet for the primus pots.

Looks like the smaller of the two weighs 7.9 oz, not 4.9 as stated above. According to REI, the pot comes with a lid, but no word on whether or not it's included in that weight. Based on the weight of my own aluminum pots, however, I think it probably does not include lid weight.

edit: of course the earlier posts are months old and everyone probably knows this by now!
