    Does Anybody Carry a Weego Onboard?

    This little thing can apparently start engines:

    Anybody have one or have experience with one?

    These devices are sold under many brand names. I have never jump started a big engine with one, but I started an outboard motor and it worked well. My only concern would be the safety of a large capacity Lithium Ion battery on a boat. Here's a good article on the issues:

      Don't just about all personal electronic devices such as

      laptops and cellphones have li-ion batteries? Seems

      most everyone has at least one onboard. Are these any

      more dangerous? Think of all the laptops that are on

      a given airline flight. If they're so dangerous would this

      be allowed?

        You are correct, but the devices that you mention have batteries that have a lot less capacity - less energy. I retired a year ago from an aircraft manufacturer and I am quite familiar with the hazards posed by these batteries and I treat them with respect. Here's a good article regarding in flight issues:

          The LIPO batteries I use in my RC cars are known to catch fire. They sell a special bag to keep the batteries in while in storage and during charging.

              So, are you saying it would be too dangerous to carry

              one of these on a boat to be used in case of a dead

              battery? Would it also be dangerous to have one in

              your car? ...in your home? ...in your garage? Are

              these never to be used at all? Costco sells them.

              Do they know the risks?

                Are LIPO the same as Li-ion? They make a distinction

                on their website that this is not Li-metal, but Li-ion. I don't

                know anything about it.

                  BoatUS just sent their "magazine" which includes this ad:

                  http://track.boatus.com/dm?id=2C4D7D...F942553AB3726E

                  Surely they wouldn't advertise something they thought

                  would be dangerous on a boat, would they? They're an

                  insurance company for goodness sakes.

                  Would anyone here admit to carrying one onboard?

                  I'm thinking it would be a great thing to have.

                    It's not like these types of batteries are going off in flames on a daily basis, but there have been a number of cases of them catching fire. The choice of carrying one is yours.

                      I think a big reason why there seem to be more failures and fires of Li ion batteries is due to the sheer number of them. Think about how many cell phones, laptops, tablets, cameras etc etc there are in the world. There are bound to be failures.

                      This is an interesting read:

                        I had my batteries die on the water last weekend. For sure the captain's fault, but as you can imagine, the admiral was PI$$ED. I can assure you I will have one of these (or similar) soon.

                          I keep one 31 series AGM battery disconnected on it's own battery switch for emergency starting when out on the water.

                          I have 4 31 series AGM batteries for my main bank.

                              Sounds like a good solution. How do you charge it?

                              I had an ACR on my last boat to isolate but keep one

                              bank charged. Worked great, but is expensive and

                              needs lots of wiring.
