Have you ever been in a situation where you desperately need to talk to someone but your phone is dead? You’re on the road heading to a race and your phone dies? You’ve been on the trail for days now and finally you need to call your ride for a pickup at the trailhead but you can’t because your phone is dead? Whatever it may be, and whether you have been in a tight spot or not, there are ways of preventing those stressful situations.

Last year I spent over $500 on batteries alone. Although I love my Energizer Ultimate Lithiums, it was time to attempt to save money and also save time. There are so many options out there now with portable solar power, power boosters, and now hydrogen power. I figured I would put some of these technologies to the test.

Brunton Pulse 1500

A few weeks ago I attended Outdoor Retailer Winter Market in Salt Lake City. If you are not familiar, it is the largest trade show for the outdoor industry. What was interesting was the amount of alternative energy/power booster brands. There were far more companies doing this than I had ever thought. A few companies stood out to me, and one of those companies was Brunton.

Brunton was founded back in 1894, by David W. Brunton. He specialized in making compasses for geologists, foresters, and surveyors. Compasses, binoculars, and GPS gear had been a focus for Brunton for some time. Although Brunton still makes navigation and optics gear, they have recently entered the solar and portable power market.

One specific product I had the pleasure to test out was the Brunton Pulse 1500. The Pulse is a the smallest power booster in Brunton’s fleet. It has a lithium ion battery built in and is powered with 1 amp.  Neatly attached is a USB and mini USB plugs, so you don’t have to worry about losing your wires. To charge your device, simply remove the mini USB cable port, and plug in your USB compatible charger. The device is square in shape (2.7” X 2.7”) and weighs in at a mere 56 grams. It also comes in 4 colors.

I took the Pulse 1500 out to 24 hours in the Old Pueblo this past weekend and it was a life saver. My Garmin Edge 500 was getting low, as I knew it would, so I plugged the USB cable into the Pulse 1500 on my 50 minute break and I was back in business. When traveling a few weeks ago in Utah, I plugged the Pulse 1500 into my computer to charge, and it took just under 2 hours, popped it in my backpack and forgot about it. While in flight at 33,000 feet, I realized my iPhone was less than 10% percent battery. I took out my iPod charger, plugged it into the integrated USB port and it charged my phone. I didn’t notice a difference between the Pulse and a wall socket in terms of speed of charge. Brunton claims that the Pulse can charge an iPhone completely without having to re-charge the booster, and they definitely fulfilled their claim.

I really can’t wait to take this on a bikepacking race or trip. I already know it will be of good use as I hate waiting around towns while my phone is charging. All I need to do is plug my phone charger in to the Pulse and throw it in the frame bag. If you are a weight weenie and second counter like me, The Brunton Pulse 1500 is a perfect option for a little boost in the backcountry.

    Awesome, great power gear for any and all situations. First time Brunton user but definitely impressed. Hope to expand my line of Brunton equipment. Thanks for the great product guys.

    Question to the reviewer or anyone else out there:
    Does this unit work for charging devices which draw very little current? I have second and third generation iPod Shuffles, which do not seem to work with chargers like this one. The current draw is so low that the unit doesn’t think anything is connected and just shuts off.

        Its been weird, I plug it in for a while and it works, but about 5-10 minutes later the Brunton Shuts down like nothing is plugged in. Is this what your are dealing with?

  3. Is there a PDF manual for the 1500? I need one.

  4. I came across this product at Walmart while checking out their camping gear. I decided to go ahead and give it a shot, the price was very reasonable and my iPhone is always dying on the trail. After a fairly quick charge at a wall socket I tested it out. It charged my phone from 30% to 100% as fast as a regular charger. I’ve taken it on 25+ mile hikes and it is wonderful. It seems to be a very solid piece of gear and is holding up wonderfully. I honestly didn’t expect a piece of Walmart gear to be this good. The weight is negligible and has proven to be an essential item for my pack. I’m looking forward to trying out more of Blunton’s products.

    I don’see how one charges the unit, and I don’t see how one uses the unit to charge a phone. I found a wire with a micro-up male, but I have not found the other end. So I want a manual too.

    The pulse 1500 I bought never charged my Iphone 5 to a full charge. It would get it 50% higher when it was freshly charged. 3 days into a backpack would only get it 20% higher. So far not impressed. I heard they have great customer service so I’ll try another one I hope

      Bill, I have been carrying larger cache batteries recently. Right now, I’m carrying a Anker 2nd Gen Astro2 9000mAh. While it’s much heavier than the Brunton, It is way more reliable.

  7. How do you charge the darn thing?

    • Hi Bridgette,

      If you follow the wire all the way around to the other side, on the underside of the unit you will see it pops out.
      That little pop-out is the USB charger.
      One side is the charging point, the other side is the charger point.
      Took me a little while to find it myself!

  8. Can it be charged by a dynamo hub ?
