With our heads in the moto-sand, we were unaware lithium jump starters existed until Weego’s motorcycle-specific press release arrived. Now on our radar, the Weego piqued both our interest and disbelief. A smartphone-sized device that can turn over, not only a dead motorcycle, but also automotive engines up to 4.6L! Nah … really?

We caught up with Weego at AIMExpo. Although no dead batteries were Frankensteined back to life while at the show, we were convinced the product was worth an evaluation. Not long after returning from the trade show Weego sent us the base model JS6.

The JS6 is dimensionally equal to an iPhone 6 (with protective case), just a little thicker, and weighs about an ounce more. It’s lithium-polymer battery has a capacity of 6,000 milliamperes (mAh, 1/1000 of an ampere) and is claimed to start engines up to 4.6L – larger than the average-size car, truck, van or SUV. The Standard JS6 retails for $109.99, and is all motorcyclists require, but if you’re of the more-is-more crowd, Weego also offers the Heavy Duty model (12,000 mAh, up to 6.4L, $149.99), and the Professional model (18,000 mAh, up to 9.6L, $199.99).

Testing the Weego JS6 was a simple matter of charging the device, then leaving on the ignition of our Suzuki GSX-S1000 for an overnight drain. Connecting the JS6 to the GSX-S’s dead battery the next morning proved no challenge to the Weego, starting up the liter-size inline-Four as if the bike’s battery was fully charged.

Having also left the ignition of my Toyota Tacoma on overnight I went directly from the dead battery of the Gixxus to the dead battery of the Taco, and the Weego spun the 2.7L engine to life with the same efficiency it did the Suzuki. A press of the Weego’s power button illuminated all four blue lights on the front of the Weego, conveying that the JS6 still retained most of its energy storage capacity. In other words, I could have jump-started at least a few more dead bike and truck batteries before zapping the Weego of its energy reserves. A few weeks after conducting the test the Weego still illuminates all four blue lights (Weego claims all its lithium jump starters lose 2% to 5% of stored energy per month).

All Weego lithium jump starters come with: Pre-charged battery pack, jumper cables (with built-in circuitry protections), wall and car chargers, 3-in-1 USB charging cord, battery terminal cleaner, carrying case, instruction manual, quick start guide.

Of course, the Weego is happy to charge electronic devices such as smartphones and tablets (Heavy Duty and Professional models will even charge laptops), but unlike more mundane external batteries the Weego can actually get you out of a fix. For iPhone 6 users, a full Weego JS6 should recharge your dead phone about three times per single charge of the Weego (iPhone 6 battery 1,810 mAh).

Like when you buy a new car and you suddenly begin seeing every similar vehicle on the road, I’ve been noticing lithium jump starters everywhere. Typing “lithium jump starter” into a search engine brings up even more competitors. Like Weego, the others come in a variety of shapes, sizes and prices. Besides Weego offering an 18-month warranty, we’re uncertain if Weego’s competitors are better or worse (this isn’t a comparison test), but we do know Weego seems to be supporting the powersports industry (there’s even a motorcycle on the homepage of Weego’s website). So, as a dutiful motorcyclist, if you’re in the market for a lithium jump starter, you should at least consider a Weego product.

    I like it. I am going to get one.

    and

    “a full Weego JS6 should recharge your dead phone about three times per single charge of the Weego”

    Does that mean a phone should have enough juice in it to jump start a vehicle? (Just can’t get to it)

    • http://motorcycle.com/ Tom Roderick

      Good question, Randy. I’ll see if I can get someone from Weego to answer.

      • Old MOron

        Looks like you persuaded Ms Toscani to enter the MOronic fray. Well done.

    • Andre Capitao Melo

      Well, you just need to know the C rating of the battery (the amount of current a battery can supply). If the battery can handle a current higher than the current used to turn a starter motor, then yes, you can, theoretically, use a phone battery to start a bike.

    • http://www.myweego.com Julianna Toscani

      When jumping a vehicle, voltage is extremely important – if you’re using one battery to jump another battery, they have to have equal voltages.

      Your bike or car battery is 12V, whereas your phone battery is 5V – for this reason, you cannot use a phone battery to (safely) jump a bike battery. This is why a 12V jump starter should never be used on a 24V system (like in large diesel engines)

      You can think of voltage sort of like electrical pressure – if you’re trying to jump your car with anything less than 12V, the pressure isn’t going to be enough. If you try to jump your car with anything more than 12V, the pressure will be too great. In both scenarios, you’re going to do damage to one or both of your devices!

    Units people! Battery capacity is measured in WHr, not A or AHr. So 6000mAHr = 6AHr So at 12V that’s 72WHr and is about 2/3 of the typical bike battery.

    An iPhone would be 1,810 mAh = 1.85AHr at 5V is 9.25WHr which is about 1/8 of the capacity rather than 1/3.

    • Andre Capitao Melo

      Your math is applied wrong, and that’s exactly why everybody uses Ah instead of Wh, so you can compare battery capacity regardless of the voltage of the appliance. A 6000mAh battery have exactly a third of capacity of a 2000mAh one.

      • http://voidstar.com/ jbond

        No. Just no. Count the number of identical cells required to create 1) a 2Ahr-5v pack and 2) a 6AHr-12v pack. The first is probably actually 2Ahr-4V and probably 1s1p. The second is probably 3s3p. Each individual cell has the same energy storage, but the second has 9 times as many of them. Hence 9 times the total energy storage. It’s also 9 times the size and weight.

        But maybe we don’t mean the same thing by “capacity”. AHr is important partly because with the C value it tells you quickly how much current can be supplied and the likely rating of the charger. But it’s always quoted with the voltage because that tells you the total energy storage.

    • http://www.myweego.com Julianna Toscani

      Battery capacity is measured in both Wh and Ah, though Ah gives you a much better idea of how much charge it holds. Wh takes voltages into account, and voltage won’t affect the amount of charge you get – so Ah is the more clear way of determining the battery’s charge capacity!

        So Julianna, how many times can your 6Ahr-12v-72WHr battery charge a 1.85AHr-5V-9.25WHr iPhone? There’ll be a little efficiency lost in the 12v-5v conversion, but small I think.

  • Old MOron

    When using jumper cables you’re supposed to connect the positive terminals first, then the negative. I guess the built-in circuitry protectors make this precaution unnecessary. Seems like a cool product. The only thing is the 18-month warranty. Most batteries last longer than that. Jumper cables basically never wear out, but they sure would be a pain to carry on your bike.

    • http://www.myweego.com Julianna Toscani

      The risk is less here because the Weego is not live (yet) when you connect the cables to the battery. The Weego should be off the entire time you’re connecting the cables. When it’s off, the cables are not live and therefore no spark risk is present.

      When jumping from another car, the cables are live – that’s why you connect the positive first, and make your final connection (the negative cable) to the chassis far away from the battery – there’s a much greater chance of a spark happening here, and you don’t want that happening near your flammable battery.

        Thank you for your reply. I had a feeling it would be something like this.

  • http://www.carnewscafe.com electricnick

    I’ve been using the Cyntur minipack for 9 months. It not only doubles as a smartphone charger, but can also handle a V8. Nothing funnier than helping a big V8 :) It has a light and flashing light warning. The best part about it, it fits under almost any seats. These things are great for many reasons.

  • w2e2b

    How long does it hold a charge if it is just sitting around?

    • http://www.myweego.com Julianna Toscani

      Lithium-Ion batteries typically lose about 2-5% of their charge per month – compare that to lead acid, which lose 10-15% per month. In other words, you can let this sit around for 6-12 months before needing to recharge. Though with any battery, it’s always good to recharge it every 3 months
