Both run PCR on a desk. The miniPCR mini8X is a thermal cycler and nothing else. Bento Lab adds a centrifuge, gel electrophoresis and a blue light in one case.

Three steps per cycle, from NEB's routine Taq protocol (M0273). A thermal cycler holds the pattern for you; without one, the tubes move between water baths by hand. Open the printable diagram

Where they really differ
The mini8X does one job. It holds 8 tubes, weighs 380 grams and runs from a phone, tablet or laptop. miniPCR sells the gel box and the blue light as separate units, so you can buy them later or use ones you already have.
Bento Lab is the whole bench in one case. Both models spin samples, run 32 PCR tubes, pour and run a gel, and light it with a blue LED. The Pro adds a variable-speed centrifuge up to 8,000 × g, a wider temperature range and adjustable gel voltage.
Capacity is the practical split. A field team writing in the journal Genes in 2020 chose Bento Lab over the 8-well miniPCR because their workflow needed more tubes per run.
Which one fits
Choose the mini8X if you already own a mini centrifuge and a gel setup, or you want the smallest cycler that runs on a battery pack. miniPCR lists a 3-year warranty.
Choose Bento Lab if you are starting from nothing and want every step of a DNA workflow in one box, or you need more than 8 samples at a time.
What it does well. One case replaces four machines, and one power supply runs them all. The supply takes 110 to 240 V, so the same unit works in any country. Bento Lab says the block uses Peltier modules and platinum resistance thermometers, and lists wells within ± 0.5 °C of each other.
Where it has been used. The field team in Genes, 2020 ran it away from a lab. Bento Lab also markets it for battery-powered work in remote sites.
What to weigh. The Entry model has a fixed-speed centrifuge and fixed 50 V gel. The maker does not publish a heated lid temperature. It warns the case is not waterproof or drop-proof, so treat it like a laptop. The warranty is 1 year, extendable to 2 or 4 years at purchase, against miniPCR's 3 years.
The alternatives. If you only need the cycler, the mini8X or a 16-well machine does that one job. A PCR thermocycler on a budget compares the small cyclers, including used units and the OpenPCR kit.
A PCR machine and gel setup on Amazon
Neither miniPCR nor Bento Lab sells on Amazon. Edvotek's EdvoCycler Jr. does. It holds 16 × 0.2 mL tubes and runs from its own 7-inch touchscreen, with no computer or phone needed.
Edvotek's M12 Ultra package pairs a gel chamber with the TruBlu Jr. blue light, which shows SYBR Safe and GelGreen stained gels without UV.
Gel electrophoresis
Edvotek M12 Ultra electrophoresis and blue light package
An electrophoresis chamber with accessories and the battery-powered TruBlu Jr. transilluminator, which lights blue-light dyes such as SYBR Safe and GelGreen at 470 nm.
The miniPCR mini8X is an 8-tube thermal cycler on its own. Bento Lab combines a 32-well thermal cycler with a centrifuge, gel electrophoresis and a blue light in one case.
The mini8X holds 8 × 0.2 mL PCR tubes and takes 8-tube strips. miniPCR also makes a 16-tube mini16X.
It suits a bench that has none of the parts yet, or work that moves between sites, because one power supply runs everything. If you already own a centrifuge and a gel box, a standalone cycler covers what is missing.
Yes, for DNA experiments such as amplifying a gene from plant or bacterial DNA. A home thermal cycler is lab equipment and is not a medical test.
Only slowly. Every PCR cycle swings between about 95 °C and an annealing step, often 50 to 65 °C, so without a cycler you move the tubes between water baths by hand. Isothermal methods such as LAMP hold one temperature but need their own enzyme and primer sets.
