Troubleshooting

There are several factors that could lead to a failed jump start. See the below list of what we’ve identified to be common culprits; if the problem persists, get in touch with us through support@myweego.com

• Clamp connection quality: a poor or minimal connection between Weego clamps and vehicle battery could result in a failed jump start – even if the light is green, it’s still good practice to ensure your making maximum contact with the terminals and to dig the clamps into the vehicle battery.
• Dirty battery terminals: build-up blocks power from easily traveling from your Weego to your vehicle’s battery.
• Low-Charged Weego: it’s always best to work with full power on your Weego if you can. Our jump starters perform better at 100% charge than they do at 20% charge, especially when jumping larger engines.
• Vehicle-specific compatibility issues: occasionally we come across a vehicle that has unique power demands that a smaller model cannot fulfill, even though it’s within our recommended engine range. In addition, vehicles with heavier electronics can sometimes create issues when jumping with a Weego; we mostly see this in push-to-start vehicles.
• Ambient temperatures: below-freezing temperatures greatly hinder a jump start as it freezes the vehicle and the Weego battery (if it was stored at ambient temperature, too). A frozen engine needs more power than usual to start, and a frozen battery supplies less power. It’s a lose-lose that could result in a failed jump.
• For models 22, 22s, 44 & 66 (does not apply to models 44.1 & 66.1)
  • Stratified battery: A stratified battery will measure a healthy voltage (~12.6V) at first, but as soon as you go to start the engine the voltage can drop to below 3V, triggering the Weego to cut off power. A battery becomes stratified when it’s been sitting around for months, and/or when it’s only driven short distances (less than 15 minutes) for an extended time. You may need a new battery.
  • Low vehicle battery voltage: The Weego initially sees a weak but adequate charge in the vehicle to jump start (3V-5V), but at soon as the engine turns over the vehicle battery voltage drops out of range (below 3V) and the Weego disconnects. In short, the vehicle battery may be too dead to start with your Weego.

The reason that your Weego wouldn’t work with your vehicle’s battery is because it was totally depleted. Weego Jump Starters have built in safety protections that set a lower limit on how many volts a vehicle battery can have and still be safely jumped with a lithium ion battery pack. Lithium ion batteries can be dangerous if not used correctly. If the vehicle battery voltage is below the lower limit, you will not get the green light. Going below the limit can cause the Weego battery to overheat and be potentially dangerous. This is the nature of all lithium ion batteries, whether a Weego or another brand.

If your unit won’t power on, won’t take a charge OR won’t charge past a few lights then it’s been overdischarged. This can happen if the unit is left ON, or if an engine pulled the Weego battery past a certain limit during a jump start.

Please reach out to support@myweego.com to let them know about this issue – we’ll receive and test the overdischarged Weego, then determine if we can repair it or if it needs to be fully replaced.

If Weego will not power on after a jump start, it needs to be connected to a charger to “reset” – this action only requires a few seconds on the charger.

• Connect Weego to provided wall charger
• If on the road, connect Weego do DC charger provided (cigarette charger) – even if your car battery is dead, it will still have enough power to reset your Weego.
• Please note: It is normal for the LED battery indicator lights on your unit to flash when you plug your unit into the charger.

Mercury Optimax outboard marine engines have a heavy power draw before the engine even starts– the electronics quickly drain any battery connected to that engine. In addition, if the battery connected to the engine is less than 11V, the engine will not turn on (the electronic systems require 11V minimum to operate).

We have experienced many instances where a Weego is connected to an Optimax, and the Optimax drains the Weego down to 11V before a jump start even occurs. When this happens, the boats engine shuts down. We advise that you purchase one of our largest models, the N66 or the JS18, for your Mercury Optimax engine. We also suggest you charge these units to 100% before use to ensure the best performance. The larger capacity of these units will help with the heavy power draw and strict voltage requirement of your engine.

Check 3 things:

1. Ensure your Weego is properly charged before use. When you press the power button and the indicator light starts blinking, it’s time to charge your Weego.
2. Weego doesn’t power on automatically – when you attach your device to your Weego, make sure you press the orange power button on the Weego to initiate a charge.
3. Your USB cord may be the issue, if not already doing so, use, the original cord supplied from your device manufacturer. Some devices are not compatible with ‘third-party chargers’, like battery packs. You may see this message on your phone or tablet. If your Weego isn’t compatible with your device, let us know by CONTACTING US

Weego will favor the charge coming from the wall, car, or other charging equipment (selfish, we know). You have to charge the Weego first, then charge your device – unfortunately you cannot do both at the same time.  However, our Tour 10400 does allow you to charge the Weego and your device at the same time!  We call this “pass-through charging”.

Batteries work hard to give you the power you need so some warmth is normal – sort of like how you heat up whenever you exercise. If you’re using your device while charging it with a Weego, it will seem especially warm. Again, this is normal; however, if you feel Weego is becoming too hot, detach your device from your Weego, and CONTACT US.
