I guess it will depend on your budget, but booster packs vary a lot in their prices.
You will find that the boosters increase in price, relative to the size of the battery inside of that unit.
We have a BEV and a fossil car in our family, and I wanted a pack with enough power, that would easily conduct multiple boosts, but not massive in its size for storage reasons.
I came across a “Halo Bolt” unit that is widely sold in the USA.
Working on the theory if it is made for the American market, it will have been designed with enough power to boost them massive 5 - 7 Litre gas
️ gobblers over there !.
The Halo unit is more expensive but also has a tyre inflation pump built in and has two USB outlets to power tablets / charge mobiles etc.
Plus a built in light
.
A neighbour left his side light on and then went away for the weekend, on his return the 12 volt battery was completely drained down to pretty much dead !.
The booster brought it back to life and still had a remaining SOC of 97%.
The Halo lives in pouch and is easily stored under the drivers seat of my ZS EV LR.
On Amazon they are £155 but after a quick search
I found that QVC in the U.K. had it on offer for £118 I think it was.
I bought another one for my son last Christmas.
