Vuse Alto Rechargeable Power Unit Kit for Microheaters - NIB - $10 (Waltham)
QR Code Link to This Post
Brand New, Factory Sealed, NIB.
USB Rechargeable Lithium 350 mAh Power Supply.
Two Complete Kits each with One (1) Power Unit and One (1) Magnetic USB charger cable.
The kits are SEALED but I found some photos on the web of the USB cables. One photo gives a partial view of the pins inside the magnetic holder.
Use with microheaters or other loads for science or electricity projects.
I needed some micro heaters for an electronics project so I bought these power supply kits. The box doesn't specify, but almost all power supplies in this category (vape products) have been lithium ion since 2016 and earlier. According to other websites, these Vuse Alto power supplies have a 350 mAh capacity and a 5V output. There is an intermittent on/off switch and a green indicator light.
They are charged at the bottom using the included 3-pin magnetic connector on the included USB-A to Vuse cable. (People are selling just the USB charging cables w/o the power supplies on-line for $8.50 plus shipping.) The module output is via a two pin connector on the top (open) end of the module and it is also held in place via a magnet. If you get some new or used "pods," you can separate the "electronics" piece (connector and micro heater) from the liquid storage portion to connect up in various ways for different experiments or research projects.
Here is a reference to a paper that can guide the use of these power units for other purposes:

"... An accurate and unbiased method for testing coil resistance is vital for understanding its effect on emissions and reporting results that are comparable ... This study proposes a robust, accurate and unbiased method for measuring coil resistance. An apparatus is used which mimics the geometric configuration and assembly of ENDS reservoirs, coils and power control units. ... Analysis shows that the proposed method is stable and reliable. ... The mean resistance and standard deviation of the reservoir/coil assemblies was shown to be 1.031 (0.067) (W) for ALTO and 1.624 (0.033) (W) for JUUL. ..."
It turns out that I went with a different micro heater option and I didn't use these.
There is no tobacco or nicotine product included with these kits. They are, basically, do-it-yourself modifiable electronic power supplies: Li batteries, cables, plastic case, etc..
