TFC's Verdict

If you use an FJ100 Strobe or Speedlight regularly, an additional FJ Mini Battery is a very useful addition to your kit. Its excellent capacity means you may not need to swap batteries often, but carrying a charged spare gives you extra reassurance for long weddings, events, and location shoots. Being interchangeable between both FJ100 lights makes it particularly convenient for photographers using the complete FJ100 system.
