Recently upgraded the battery on my 2020 Verreal F1 to the 10Ah one, definitely faster with this 4amp charger than my previously slower 1.5/2a charger, only took ten days for delivery to the UK too. Noticeably larger overall, and heavier than my stock charger. However, the main downside was being sent a US plug adapter instead of UK one... Thankfully, I have one lying around but this shouldn't have been an issue in the first place when ordering... It takes 2hrs 30mins to fully charge my new 10Ah battery, must've been 4hrs+ with my previous 7Ah battery pack/1.5/2a charger. Very useful for long skating trips!
I am happy with this product as it saved me waiting time.
