Dovpo DT-50 4000 mAh from VapeB2B
The new Dovpo is a safe advanced personal vaporizer powerhouse that features an incredible 4000 mAh battery built into the device.
In terms of safety, this has it all:
- Working voltage: 3.3 to 4.2 volts
- Output power: 7-50W (adjustable wattage)
- Adjusted according to a load resistance (smart match)
Resistance: 0.2 to 0.3 Ω power: 20-50 watts
Resistance: 0.4 to 0.8 Ω power: 15-40 watts
Resistance: 0.9 to 1.4 Ω power: 10-30 watts
Resistance: over 1.5 Ω power: 7-20 watts
- Intelligent memory: retain memories of the last resistance adjustment of power parameters, recycle use the same power will automatic matching
- Load capacity: minimum resistance 0.2 Ω
- Output short circuit protection
- Low-voltage automatic protection: voltage lower than 2.5V
- Automatic Temperature protection: temperature over 70 C (158 F)
- Lithium battery automatic protection: battery won't discharge over 25A
- Automatic fuse protection: voltage more than 30A
- Built-in lithium battery capacity: 4000 mAh
- Charging voltage: Micro charger DC5V
- Max current charging: 800 mAh
Although not in the specs, this also features RMS. This is a method of constantly monitoring the coil resistance and adjusting power sent to the coil in real time. Coil resistance does change based on heat, age, and the type of liquid you use. RMS provides a more consistent vape experience.
The unit we received for testing and review from Everzon is a silver unit. Quite frankly, I am not sure why these devices feature pictures directly etched or screen-printed on the mod – they add no relative value and usually have nothing to do with the mod at all. This one has a scorpion on it. I'm glad this is a silver unit, the graphic is barely visible.
The Dovpo DT-50 is available in two colors as shown at the right: Black and Silver. While slightly "boxy", they do have bevelled edges and are very comfortable in the hand.
The OLED screen is a nice size with display that is high contrast, larger than usual text sizes and very easy to read.
The fire button is along its width ... that may take you some time to get used to. Most APVs have the fire button on the depth edge. I found the most comfortable vaping position by having the device with its width facing you instead of its depth. There is a slight button rattle and all the buttons have a tactile click.
One VERY nice feature is that the micro USB charging port is on the side of the unit. Finally, an APV that you can stand up and plug in beside you instead of laying on a table or floor – and little possibility of scratching the visible surfaces.
The top of the Dovpo DT-50 has an philips head adjustable brass screw and nice air flow slots that add to the overall look of the device. The 510 connector is buttery smooth. While not able to confirm this, it does look like the threads are stainless steel.
While you are looking at the picture at the right, notice the fire button. The possibility of inadvertently firing is virtually eliminated with the fire button surrounded by a fixed ring that also offers protection for the + and - buttons.
The package does include a micro USB charge cable, and the instructions clear state that you should NOT vape while charging – this is not pass through charging. The package also includes a mini philips head screw driver and the device does have four screws at the top and four at the bottom. I can't see any need to open this up, though, the battery is fixed and not replaceable. I do suspect that when the charge life cycle is done with, some users may try to replace the li-po battery themselves.
The Dovpo DT-50 is nice and light. The case is made mostly of aluminum (with some stainless steel components as I pointed out) and has a li-po (lithium ion polymer) battery. Li-po batteries are much lighter than the standard round lithium ion batteries (like the 18650) that vaper are used to ... but they do introduce a new set of risks that all should be aware of. Li-po batteries are much lighter because they have no metal outer case, they are usually packaged in a plastic "pouch". Some are packaged in a thin hard plastic (like cell phone batteries). The risk to vapers is that when these are dropped, they should not be put back into use.
I need to point out that I will not be opening the case up at this point in the tests and review. I will do that at a later date. The DT-50 is planned to be featured in a streaming broadcast shortly and I don't want to risk damaging the device before the broadcast – so check back again for the tear-down portion of the review.
Before I write up my final thoughts, I want to extend KUDOS to Dovpo one one aspect of the DT-50's design and electronics: The user instructions clearly state that the user should NOT vape while charging the DT-50 through the micro USB port. Dovpo have disabled the fire button when the micro USB port is plugged into a charger ... WELL DONE DOVPO. Thank you for helping vaper's safety. And, second set of KUDOS: the buttons are non-standard but I really like the layout. I keep the buttons facing me, fire with my thumb – with the OLED facing me as well, it is very easy to glance at the OLED screen after inhaling for information – a small thing, but a benefit nonetheless.
So, what’s the verdict? Is it worth it?
As the above paragraph mentions and the safety features above indicate, Dovpo has well thought out this device with vaper's safety in mind. It is well designed, well engineered, and very well built. The edges that are handled by the users are fairly smooth, the DB-50 is very comfortable to hold and quite light. With its 4000 mAh battery, this should hold enough power for an all day vape – the only caveat is the RMS feature will eat up some of that power, but it should be miniscule enough to still get a full day of vaping before needing recharging. I do recommend the Dovpo DT-50 with a note that users switching between devices will have a bit of a challenge with the fire button location. Having that button along its width (instead of the usual along its depth) is a bit non-standard – but it is also a very safe button with its outer ring protecting against mis-firing.
