Quick answer
If you need the absolute fastest recharge and don't mind the higher price, choose the Super Charger. For most daily work, the Fast Charger offers solid speed at a lower cost.
Speed vs. price: the core trade-off
The Super Charger charges 4x faster than the standard Blue Ion charger, while the Fast Charger is 2x faster. That extra speed costs about $16 more and may be worth it if you rotate batteries through heavy use.
Both chargers communicate with the battery to optimize charging and protect against overheating, so your batteries stay safe either way.
Workspace fit and convenience
Both models offer two-position wall mounting and LED charge status indicators. The Super Charger adds a 6-foot power cord, which gives you more flexibility in where you mount it relative to an outlet.
If you plan to mount the charger near an existing outlet, the Fast Charger's shorter cord is rarely a problem.
Which charger should you pick?
- Choose the Super Charger if: You frequently drain multiple batteries in a day and need the quickest turnaround to keep working. Plan to mount it within reach of a 6-foot power cord for maximum placement flexibility.
- Choose the Fast Charger if: You want a reliable, faster-than-standard charge without paying extra for top speed. Check your typical battery level—the 45-minute claim applies when starting at 25% or one LED.
- A note on compatibility: Both chargers work with all Kreg 20V Blue Ion batteries, so your existing battery collection is covered either way.
