Every heated product runs on the right power and care behind it. The BERTSCHAT® accessories range brings together spare batteries, chargers, cables and heated add-ons for home, desk and bike, so you can keep your gear performing season after season. Whether you need a replacement battery or want to extend warmth to a new part of your day, you will find the right part here.
What the accessories range covers
The range splits into three practical groups: power, connectivity and heated add-ons. On the power side you will find replaceable batteries in a range of capacities, alongside high-capacity powerbanks and 12-volt systems built for jackets and vests with a large heating surface. Browse the full selection of battery packs to match the right capacity to your product.
For charging and control, our cables and chargers keep batteries topped up and ready, while a remote control lets you adjust heat settings on the move. Beyond wearables, heated add-ons extend comfort to the rest of your day: a heated desk pad for cold hands at the keyboard, a chair warmer for the home office, or a heated bike saddle cover for the morning ride.
Each battery type is matched to a specific use, from lightweight packs for undergloves to 12-volt systems for large heating surfaces. If you are replacing a battery, check which capacity your product uses in the product manuals before ordering. To keep everything in good condition, the range also includes care items such as a laundry bag and a cleaning kit for washing your heated gear safely.
Choosing the right accessory
- Battery capacity: Higher mAh means longer heating time, but also more weight. Lighter packs suit gloves and precision use, while larger capacities give extended warmth across a full day outdoors.
- Voltage and product type: Match the battery to your product. Smaller USB packs power gloves, socks and insoles, while jackets and vests with a large heating surface need high-capacity powerbanks or 12-volt systems.
- Charging setup: A DUO-charger charges two batteries at once, and an extension cable adds reach where you need it. Check your existing connectors before adding to your setup.
- Heated add-ons: Choose add-ons based on where you feel the cold. Cushions and chair warmers suit the home and office, while a saddle cover keeps cycling comfortable.
- Care and maintenance: Wash heated items in a laundry bag to protect the wiring, and use a cleaning kit for leather items. Regular care extends the lifespan of your gear.
