I’ve been using eBoostr daily on two indentical CF-M34 Toughbooks. Both are used in field on battery. I’ve done different tests swithing batteries between them with one having eBoostr and one without when I first started using eBoostr. Now both units are running eBoostr, because I’ve seen a consistant 30-40 minute increase in battery use with eBoostr.  Cold weather in area has decreased that to 30 minutes max. because of the HDD heater.  Good job!  Looking forward to adapting a solidstate HDD to see how far I can push these mini-harden laptops. thanks!
