Questions and answers
- Which is the better deal per battery?
- The DCB205-2 two-pack. At $110.14 for two packs it is about $55 per 5.0Ah battery, against $139.00 for one POWERSTACK at Home Depot as of November 3, 2026.
- Is the POWERSTACK worth the extra money?
- Only if size and weight matter to you. It is slightly lighter and more compact and charges in about 1.5 hours, but you get one battery instead of two for more money.
- Do both fit my existing DeWalt 20V MAX tools?
- Yes. Both are 20V MAX packs and work with the same tools and chargers, so you can mix them in one kit.
- Which lasts longer on a charge?
- Both are 5.0Ah, so runtime per charge is close. The DCB205-2 gives you a second pack, so total work time between wall outlets is roughly double.
- Does either include a charger?
- No. The DCB205-2 listing states the charger is not included, and the POWERSTACK is sold as a battery only.
- Which is better for tight spaces?
- The POWERSTACK. Its pouch-cell design is smaller at 5.2 x 3.3 x 2.2 in, which helps on compact tools and in tight spots.
