First off, let me say that the Timesvape Heavy Hitter is a purely mechanical mod, which means it demands a solid understanding of battery types, Ohm's law, and the various safety rules and habits that this style of vaping requires. It's definitely not for beginners.

With those important points covered, the Heavy Hitter by Timesvape is a fine tube mod that accommodates both 21700 and 20700 batteries. Despite being a pure mechanical device, it includes thoughtful features like an internal Delrin sleeve to prevent accidental firing in case of a torn battery wrap, a fire button lock, and a battery vent hole. The packaging consists of a rigid cardboard box with a vintage feel, featuring an old-school boxer design. Upon opening it, you'll find the Heavy Hitter's inner packaging, which includes a plastic-coated pouch and a blue net. Beyond providing protection, this is also a reusable pouch you can use whenever the tube isn't in use to remove as much air as possible and prevent oxidation, especially if you don't have a suitable case.

In addition to the Heavy Hitter itself, the protective packaging also contains a second 26mm top cap, allowing for the use of atomizers smaller than 28mm to improve the overall aesthetics. Inside the pouch, you'll find two spare springs and an O-ring, whose purpose will be explained later. Lastly, a microfiber cloth for cleaning is also included.

The Heavy Hitter I received is made of copper, although there are also black-plated copper and brass versions available. In my case, the empty weight (without the battery) is a substantial 197 grams, so Timesvape definitely didn't cut corners on materials. For safety, there are vents carved near the top cap to allow for battery venting and prevent accidents.

Timesvape also didn't hold back on customization. Instead of just including a simple beauty ring, they opted to provide two top cap options, a 28mm and a 26mm, making it easy to pair with a wider variety of atomizers. Both are equipped with a 510 threading and have the Timesvape logo and the mod's name engraved. Since my version is copper, and this applies to the other available materials as well, I recommend using an abrasive sponge to avoid scratching.

The top cap unscrews via a well-machined thread, revealing the Heavy Hitter is a mod with a hybrid connection. This means there is no central pin, and the battery makes direct contact with the atomizer's 510 pin. This brings us back to the safety point: only use atomizers with a protruding positive pin and frequently check all of its insulators to ensure they are intact and prevent short circuits. Inside, you'll see a black Delrin sleeve that lines the entire interior of the tube. This should prevent issues in the case of a torn battery wrap, but the golden rule of inspecting your battery before insertion always applies.

The battery can be inserted from either the top or the bottom by opening the block that houses the fire button and the contact cup. This block doesn't have a thread; instead, there are three tabs that, when aligned with the three grooves on the mod's body and given a short twist, allow you to screw or unscrew the entire mechanism. The cup, with its gold-plated center, is what makes the contact and allows for firing.

To unscrew the floating "pin/cup", you can grip the white/beige section and unscrew it clockwise. When it's new, it has a bit of friction, but a little patience is all you need to unscrew the entire mechanism in one go. The photo shows an exploded view, in order, with the ball-shaped pin in the center, which connects with the white/beige cup to create the contact. The spring, on the other hand, allows the battery to "self-adjust" when inserted, so you don't have to unscrew and re-screw everything to ensure the battery and the atomizer's pin are making solid contact.

Timesvape also paid attention to the aesthetics of the fire button, engraving "Be Tenacious, Hit Heavy" and a boxing glove, but also to safety. By twisting the button (just the button, not the sleeve) a quarter turn, you can physically lock and unlock the button, making it safer and eliminating the need to remove the battery for quick transport.

By unscrewing the copper sleeve, which has a well-machined thread, you'll find that the button's action is enabled by a spring (with a spare included in the parts kit) held between the button and the Heavy Hitter's bottom cap. To release the spring, you have to unscrew the protruding part of the fire button.

The button screws onto the gold-plated ball pin section we saw earlier, with the spring inserted, as shown. The twist-to-lock system works thanks to the grooves around the back of the ball pin. It's easy to unscrew and re-screw, as frequent cleaning is necessary, just like with the entire copper tube, which is a known consideration when buying a copper product.

The Heavy Hitter has a top-class ratio of cost to material quantity and detail finishing. Despite its size, which is due to 21700 battery compatibility, it maintains a graceful appearance thanks to the central narrowing. The 21700 batteries, with their high discharge amperage / CDR (often with a minimum of 20A, but also 30A and 40A; I recommend looking for batteries with these values), not only provide safety by not stressing the battery itself, but also offer significantly better battery life than 18650s. This is certainly not a mod to learn on if you're new to mechanical vaping (a regulated box mod in bypass mode with all its protections is better for that), but it can be the perfect first fully mechanical tube mod after you've mastered the concepts and rules to make mechanical vaping as safe as possible.
