MINIWARE DS213 pocket scope, 15 MHz, 2 analogue and 2 digital channels review
A pocket oscilloscope with two analogue and two digital channels, 15 MHz bandwidth, 100 MSa/s sampling and 4K sample depth, a 3-inch colour screen and 8 MB of storage exported over micro-USB.
The bottom line A beginner’s pocket scope whose distinctive feature is its two digital channels. Its bandwidth, sampling and depth are the lowest of the five, and the listing is right to aim it at beginners.
The DS213 listing, bullet by bullet
Five bullets and a warning: 2 analogue and 2 digital channels, 15 MHz, 100 MSa/s and 4K sample depth; a compact size for electronics beginners; a 3-inch 320 × 240 colour screen and a 1000 mAh lithium battery; 8 MB of storage and micro-USB export to a computer; uses in teaching, repair and engineering; and a capitalised warning not to charge during measurement.
Digital channels on a MINIWARE pocket scope
Two logic channels beside two analogue ones. On microcontroller projects, seeing a clock and a data line alongside an analogue signal explains timing problems that a two-channel analogue scope cannot show together.
The lowest figures of the five
15 MHz and 100 MSa/s are enough for audio, PWM and slow serial lines. They are not enough for fast digital edges, and the listing does not claim otherwise.
A warning in capitals
Charging during measurement is forbidden in the listing’s own emphasis. Measuring with a charger connected can join the scope’s ground to the charger’s, and the maker’s warning is the instruction to follow.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking roughly 155 €.
The British Amazon catalogue lists the product, yet no seller was offering it.
The American Amazon store returned no entry, so the buy button there opens a search rather than a missing page.

Questions makers ask before buying
What are the digital channels on the MINIWARE DS213?
The first bullet lists 2 digital channels alongside 2 analogue ones. They are used to view logic-level signals; the listing does not describe decoding.
Can the DS213 be used while charging?
No. The sixth line of the listing warns, in capitals, not to charge the oscilloscope during measurement.
50 MHz · 250 MSa/s · 2 channels · 128K memory · resistive touchscreen, 3.98 in · DDS signal generator, 7 waveforms · 3000 mAh, over 10 h
A two-channel handheld oscilloscope with 50 MHz bandwidth, 250 MSa/s sampling and 128K memory, a 3.98-inch resistive touchscreen, a built-in seven-waveform signal generator and a 3000 mAh battery.
Best for: Car electronics and field diagnostics, where a battery-powered scope and generator in one hand is the point.
A two-channel 50 MHz handheld oscilloscope at 250 MSa/s with a 10,000 waveforms-per-second refresh, an independent 4½-digit true RMS multimeter, and a USB-C port that shows saved images and CSV waveforms as a flash drive.
