Yes, only three dollars more. Can anyone advise if they really are comparable? Similar technology? And benefit to go for one or the other. More concerned with jump starting a weak battery than anything else.

Thanks i was looking for a lithium ion version to replace my old lead acid Canadian Tire one and with coupon code that's definitely a winner.

Who design this stupid booster?sapphire68 wrote: ↑ I purchased this model last month and found out some quirks about it which prevented it from helping me start my car when I needed it last week. More details below.
TL;DR: If your car/target battery is higher than 9V, it may not give you a boost
A controller inside the inline fuse-box measures the voltage from the target battery once the clamps are connected, and through some testing I found that under certain conditions the controller will not close the circuit between the portable bank and the clamps, therefore there will be no output at the clamps. My findings are:
- If the measured voltage at the clamps is less than 9.0V, then the controller will 'send' the output from the portable bank and everything will work
- If the measured voltage at the clamps is more than 9.0V, then the controller will disconnect the output from the portable bank and the target battery will not be boosted
Unfortunately for me, my car's battery was at 10.9-11.0V which was low enough to not start the car but not low enough for the controller in the fuse-box to allow boosting to occur. I'll probably need to DIY/buy a straight cable to get around this controller issue, which becomes an inconvenience and added cost. Apparently some older shipments have a fuse-box with a bypass button, but mine does not have this feature. I e-mailed Trekpow and they said the new ones will not have a bypass button.
Just something to keep in mind.

Any link?Scote64 wrote: ↑
There's another alternative to consider these days: the super-capacitor jump starter. No lithium-ion battery, they use a super-capacitor instead. The capacitor can't store a charge for a long time without it leaking away, so how they work is that you connect it to your weak battery for a few minutes and let it build up charge, then it can dump all that charge at once into giving you a boost. If your battery is too depleted to do even that much, you can ask someone else nearby to connect it to their car for a few minutes to build up charge - no need to string jumper cables between the cars.

Was just going to add that this does not seem to be available via amazon.ca. I like the idea though, you just leave it in your car, even on the coldest nights, and you have no worries the next morning.Scote64 wrote: ↑ Super-capacitor jump starter:
