Note: the reviewer appears to not have read the manuals. If the batter is REALLY drained (>2 volts) there's a manual override button on the GB40 that needs to be used. None of the reviews show that being done. Just sayn'.

This is what I purchased several years ago.

None of my previous purchases were worth a d*mn.

Battery Tender is a respected name. I have never seen any comparisons with other jumpstarters.

I have a battery tender I use for battery maintenance, and a GB40 for emergencies (none on the water so far)

I also have a Battery Tender for maintenance (not for the Mac).

What tuned me into that company was a customer who collected Corvettes. He had ten that I saw. He had a Battery Tender for maintenance charging on each Vette.

I have used Battery Tenders on my entire car collection for over 10 years... and also on the Mac. They work very nicely.

Interesting.

I have a cheap super small jumper pack I got on Amazon. Have never needed it on the boat, but it managed to jump start my truck when it was -5f degrees outside. Quite impressive.

I put this in the category (like pull starting my outboard) of an item I hope I never need, but if I need it, I really need it.

Gotta Act Quick
The Imazing battery booster is available for 59.00 Amazon lightning deal for the next 4 hours.
Can't beat the price.
