CCELL Silo

The CCELL Silo uses the widely adopted 510 thread. That means virtually every oil cartridge with a 510 connection works. No manufacturer lock-in, no proprietary adapters. Anyone who already owns cartridges can get started straight away. The magnetic adapter between the battery and cartridge sits securely and does not wobble. A short twist is enough to insert it.

The Silo does without controls completely. As soon as you draw on the mouthpiece, the sensor detects the airflow and activates the heating element. No accidental switching on in your pocket, no button pressing. This makes the Silo particularly suitable for everyday use. Anyone who wants to vape discreetly on the go will find few simpler devices.

The internal 500-mAh battery lasts several days, depending on the cartridge and draw length. Charging is via Micro-USB on the underside. An LED shows the charge level in three stages: green, blue, red. The Silo is fully charged in just over one hour. For occasional users, one charge easily lasts five to seven days.

CCELL is best known for its ceramic heating elements. The patented ceramic coil in CCELL cartridges provides even vaporization without dry draws. Cartridges from other manufacturers also work, as long as they have a 510 thread. Anyone who wants the best performance should still choose original CCELL cartridges — the tuning between battery and cartridge is then optimal.

The CCELL Palm Pro offers three voltage levels and a preheat function. By contrast, the Silo stays with a fixed voltage and focuses on maximum simplicity. Anyone who wants to adjust their vapor output is better served by the Palm Pro. Anyone looking for an uncomplicated device without settings is well served by the Silo. Both share the 510 thread and the magnetic adapter.

The Silo is optimized for CCELL's own 510 cartridges, but works with all common 510 cartridges. CCELL cartridges use ceramic heating technology, which provides even vapor production and clean flavor. Compared with cotton wicks, ceramic does not scorch and lasts longer.

When buying cartridges, it is worth looking at the viscosity of the oil. Thick oils need the ceramic CCELL coil; thinner oils also work with simpler cartridges. The Silo automatically detects the resistance and adjusts the power.

With 500 mAh and draw activation, the Silo is designed for uncomplicated use. No button, no display -- just draw. A full battery lasts from half a day to a full day, depending on draw length. Charging is via Micro-USB at the lower end.

The magnetic housing protects the inserted cartridge from drops and scratches. The Silo fits in any trouser pocket and weighs under 50 grams. For users looking for a discreet solution with no learning curve, the Silo is one of the simplest options in the CCELL range.
