Get everything you need to power your Coolest Cooler Blender in one box. The Vonblay BAT101 combo set pairs a brand-new 21V 2100mAh replacement battery with a dedicated BAT101 charger, so you can start blending the moment it arrives — no hunting for a compatible charger separately. It is the ideal starter kit for anyone whose original battery or charger is lost, damaged, or no longer holding a charge.

Compatibility
The battery in this combo is a direct replacement for the Coolest Cooler Blender battery. The included charger matches the BAT101 charging profile for a safe, stable charge. If you want extra runtime, add our two-pack batteries as a spare — they share the same form factor and charge with the same adapter.
The Convenience of a Complete Set
Buying the battery and charger together saves you the guesswork of finding a matching adapter. Everything is tested to work as a system: the battery delivers the runtime, the charger keeps it ready. Instead of buying parts separately and hoping they are compatible, you receive a matched pair that is guaranteed to work together out of the box.
New Battery, No Rebuild Wait
This is a brand-new battery, not a rebuilt pack. You skip the mail-away rebuild process entirely — no shipping your old battery off, no weeks of waiting, no doubt about cell quality. Order today, blend tomorrow. The included charger means you are never dependent on a worn-out original adapter.
Runtime & Everyday Use
The battery provides approximately 20–30 minutes of continuous blending per charge, enough for several drinks at a time. Use it at home for meal prep, then toss the combo in the car for a day trip. The universal-input charger handles different outlets, making it travel-friendly.
Care & Maintenance Tips
Store the battery at room temperature and avoid long periods fully discharged. Recharge every couple of months if stored seasonally. Keep contacts clean and dry, and let the charger taper off naturally when full.
What’s in the Box
- 1 × BAT101 21V 2100mAh Li-ion battery

Warranty & Support
The combo set carries a 12-month warranty covering both the battery and the charger against manufacturing defects.
Who Should Choose the Combo
The combo is best for anyone starting from scratch — lost charger, dead battery, or a blender pulled out of storage after years. One purchase covers both essentials, so you can blend the same day the box arrives. It also makes a thoughtful replacement gift for a friend who still loves their Coolest Cooler but has given up on a faulty battery.
Shipping & Delivery
The battery and charger ship together within one to two business days, with full tracking on every order. Standard international shipping is available for customers in North America and Europe. Please allow 8–15 days for delivery after your order ships.

Was skeptical about a third-party replacement and having the spare charger means I never wait around. Blends ice like the day I bought it.
Finally replaced the pack that came with the cooler and the kit had everything needed to get blending again. Five stars, no complaints.
Kept seeing ads for this and gave it a shot and having the spare charger means I never wait around. Couldn’t be happier with the purchase.
Decided to try this instead of buying a new cooler and the kit had everything needed to get blending again. Will buy again from this brand.
Picked up two so we always have a charged one and the battery + charger combo saved me from buying parts separately. Solid build quality, feels OEM.
