Solar charger 70W (5V-20V)

The products are heated using power from the rechargeable lithium-ion battery. The heat is generated by the sewn-in carbon fiber threads located in the heating zones and can be easily adjusted using the button to three different levels: high, medium, and low.

Yes, the 5,000mAh XL batteries that come with Base Layer V8 and V7 are compatible with all our clothing when using a dongle/conversion cable.

A dongle can be purchased separately or together with the XL battery.

The new XL battery with a capacity of 5,000 mAh is charged via USB-C.

Although the battery is 7.4V, it can be charged with a 5V power bank, as there is a built-in step-up converter in the battery that converts 5V to 8.4V (which is required to charge a 7.4V battery).

The 2600 mAh clothing battery is charged with a 220V charger and also has a 5V output (for charging mobile phones, etc.).

The Base Layer V7 + V8 comes with an XL battery of 5,000 mAh for each part. It is charged via a USB-C charger, which is not included. The battery can also be charged with a 5V power bank, as there is a built-in ‘step-up’ in the battery that converts 5V to 8.4V. The Base Layer (under Outlet) comes with a 2,600 mAh battery and charger, unless you have opted out of this during the purchase process. Here, you can choose the new XL battery with dongle (conversion cable) instead. For the soles, you can choose to use regular 5V power banks or our combined hand warmer/ power bank with 5,000 mAh or 10,000 mAh, respectively, which also has an (important) on/off function so you don't have to plug it in/out every time you want to turn the heat in the soles on/off. 5000mAh provides approx. 5 hours of constant heat on a single charge – 10000mAh = 10 hours.

Each product has recommended heating times for the batteries.
Depending on the heat level selected, the following recommended times apply to clothing (to make it easy to remember): 2600 mAh: Red = 2 hours - Yellow = 4 hours - Green = 6 hours. 5000 mAh (new XL battery): Red = 4 hours - Yellow = 8 hours - Green = 11 hours Heavy-duty gloves, mittens, jackets, vests, etc. last a little longer than the recommended times, so add about +10%. It is also important to note that the battery's full capacity is only achieved after 8-10 full charges and discharges. If you start using your clothing and find that the battery does not quite live up to the recommended heating times, this may be due to a battery that is still ‘young’. The accompanying battery instructions should always be followed.

'Warm hand in a warm glove'.
In general, make sure to turn on the heat before you get cold. This is important, as the technology is designed to keep you warm, not necessarily to heat you up. Therefore, you may find that you don't get very warm, but on the other hand, you won't freeze either – only when the heat is turned off.

Please note that the underwear, which is close to the body, becomes very warm at the highest heat setting (Red). This setting is only intended to provide a “burst” of heat here and now (we recommend a maximum of 10 minutes at a time on RED), after which you should turn it down to medium (Yellow) or low (Green). This will also make the battery last longer on a single charge.

Yes, in principle it is possible (but only if used incorrectly).

The underwear fits snugly and can become very hot (54°C*) at the highest temperature setting (Red). If the body cannot absorb any more heat in the blood and nerve pathways, the heat is “rejected” by the body and the skin remains at 54C - this can cause red marks.

If you experience discomfort in the form of “tingling or prickling” or similar, it is of course important to turn down the heat immediately.

We recommend a maximum of 10 minutes at the highest setting, RED, at a time!

We do not recommend that the underwear be used by children, disabled persons, or persons with reduced sensitivity without supervision.

No, it cannot.

The garment has a built-in overheating protection (mechanical TPC) that automatically turns off the heat if the temperature exceeds 55°C.

In addition, there is a safety circuit in the battery that also shuts off if there is a voltage surge in the garment.

When the skin has warmed up and can no longer absorb any more heat, it is important to turn down the highest temperature setting (red), as otherwise you risk getting red marks. Keeping 55°C directly on the skin for a long time can have consequences, and we therefore do not recommend that the clothing be used by children, disabled persons, or persons with reduced sensitivity without supervision.
