The lightest item on this list weighs 1.94 ounces, according to its listing. That is a working monocular, small enough to forget in a coat pocket until the moment you need it.

$10 technology gadgets generally work similarly: compact, single-use, and easy to miss until they help you out with a task.

5 tech gadgets under $10

Gadinsider has compiled a list of five of those. The list actually extends to some surprises when it comes to affordable gadgets. The thing with them is that they revolve around a good idea, like a magnetic feature of the base of the speaker and a lighter without fuel.

Among other things, brands like HDAJY, heetipuk, FineInno, YANGVVIA and ENGFYADSY will be featured on the list, and since the claims on the gadgets are made by their Amazon listings, we marked them accordingly.

1. HDAJY mini monocular telescope

This is a pocket-sized 30 x 25 monocular with a metal barrel and a rubber outer layer. HDAJY says it suits hiking, birdwatching, concerts, ball games and stargazing and that adults and children can use it.

Key features and specs

Magnification: 30 x 25, per the product title
Size: 3.7 inches long, 0.95 inches in diameter
Weight: 1.94 ounces
Focus: Manual
Build: Metal barrel with rubber outer, per HDAJY
Weather resistance: Described by HDAJY as waterproof and moisture-proof
Colour: Black

Performance

It has only one eyepiece, making it smaller and lighter than the binoculars. The weight of HDAJY is less than two ounces, which makes it portable. It does not have auto-focus, meaning that the user will need to do it manually. The product claims that it is water resistant, although there is no rating to prove the extent.

Pros

Pocket-sized and very light
Metal barrel with rubber outer layer
Suitable for hiking, birding and events, per HDAJY

Cons

No phone adapter is listed, though the listing mentions smartphones.
The waterproof claim comes with no test standard.
Listed specs conflict, so check the details before relying on them.

3. Heetipuk magnetic Bluetooth speaker

The heetipuk is a mini Bluetooth speaker with a magnetic base, so it sticks to metal surfaces such as fitness equipment, a fridge or golf cart bars. It also works as a phone stand and has RGB lights.

Key features and specs

Output: 5 watts, mono
Connectivity: Bluetooth 5.3, plus a TF card slot
Battery: Up to 7 hours at 70% volume, per heetipuk

Extras: Magnetic ring for non-magnetic surfaces, lanyard, built-in microphone for calls, TWS pairing for two speakers
Lights: RGB, switched manually

Performance

The magnet is where this device shines. The speaker can be attached to sportswear or refrigerator doors through the magnet. There’s a TF card reader which allows the user to listen to saved songs without a phone. It uses mono audio in which only one channel can be generated using one speaker, but two heetipuk speakers can be used in TWS mode.

Pros

Magnetic base and ring for mounting
Bluetooth 5.3 and a TF card slot
USB-C cable, lanyard and magnetic ring included

Cons

Mono output only
The battery figure is for 70% volume, so full volume may be shorter.

4. YANGVVIA electric lighter

This is a USB-rechargeable plasma lighter that uses touch ignition and has no fuel or flame, per the listing. YANGVVIA sells it in a "Dragon" design, with a battery indicator of four blue dots.

Key features and specs

Ignition: Touch, with no button to hold
Power: Rechargeable by micro USB; cable included
Fuel: None; electric
Battery indicator: Four blue dots
Size and weight: 3 x 1.3 x 0.4 inches, 1.76 ounces
Material: Metal and plastic
Weather: Windproof, but not waterproof, per YANGVVIA
Design: Dragon

Performance

Unlike ordinary lighters that produce a flame, the plasma lighter produces an electric arc that requires recharging, not refilling. You can use the battery gauge to monitor the battery status, and this is important as the arc will cease once the battery empties. Being wind-resistant but not water-resistant, ensure that it remains dry at all times. It is appropriate for lighting candles among other similar purposes, although no charge life has been mentioned.

Pros

No fuel needed; recharges over USB
Four-dot battery indicator
Windproof, per YANGVVIA

Cons

Not waterproof
Charges over a micro USB, an older connector
No battery life or ignition count is given.

5. FineInno desktop vacuum cleaner

The FineInno is a small cordless vacuum for desks, keyboards and car seats. It is meant for crumbs, dust, paper bits and pet hair, per the listing.

Key features and specs

Power: 2 AA batteries, cordless
Run time: 2 to 2.5 hours, per FineInno

Filter: Cloth
Use: Desk, computer, car
Picks up: Crumbs, paper, dust, cat hair, eraser shavings and similar light debris, per FineInno
Noise: Described by FineInno as low-noise

Performance

A device like this is made for light tasks, including removing bits from keyboards and erasers. It will be useful because of its compact size. FineInno uses a battery that lasts up to 2.5 hours, but no suction capacity is given in the listing, so there is no way to tell about its effectiveness with heavy dirt.
