Two ports for charging gadgets, a display for displaying the percentage of charge, a built-in flashlight, affordable price.
 
 
Thick body.
 

Hoco B20-10000 is a spare tank ready to come to the rescue for "refueling" gadgets, as they say, in the field, when access to the outlet is not expected in the near future.

The first thing that captivates a mobile battery is a tasty price tag. Especially in light of the claimed capacity at the level of 10000 mAh. Of these, over 6500 mAh is available for charging gadgets. The rest is lost in the process of converting the voltage from 3.7 V on the external battery batteries to the standard USB bus voltage (5 V). Also, part of the energy goes along the way when the Power Bank is heated and exposed to low temperatures.

Both ports of the mobile battery output current up to 2.1 A. The gadget "refills" its tanks through the microUSB input. By the way, in the company of interface openings there are two bulbs of a built-in flashlight, which can be useful in the dark (when going out into nature, returning home through dark alleys, etc.).

The indication of the remaining battery charge of the model is displayed on the digital screen as a percentage. It is harmoniously integrated into the plastic case of the device, decorated with carbon fibre. The only complaint against the "jar" is the excessive thickness of the case (24 mm). On the other fronts equal to the battery, you still need to look carefully. In the low-cost price category, the Hoco B20-10000 rules the ball virtually single-handedly, towering over its closest rivals by a whole head in terms of functionality.

 
High-quality steel body, reliable locking mechanism, stylish appearance.
 
 
Tight valve button, sometimes there are leaks in the area of the cap thread.
 

The Rondell trademark has gained fame thanks to high-quality dishes and all kinds of kitchen accessories. However, some of the brand's products live not only in the kitchen, but can settle in a bag, a car interior or a cup holder on board a stroller. We are talking about a thermocup with the index of the RDS-836 model, the heat and cold inside of which are stored for up to 4 hours.

The main actor in the design of the product is a double flask made of high-quality stainless steel, which has a capacity of 400 mL. The outside of the mug is also metal, moreover, to heighten the effect, the coating of the outer "wrapper" is made matte. It looks very impressive, but over time it actively acquires small scratches and slightly loses its presentation.

In order to drink hot tea on a frosty winter day or take a sip of refreshing lemonade in the hot summer heat, you need to cling to the drinking cup with your lips, which is an integral component of the lid made of safe food-grade plastic. The contents are in the flask "under the lock" of the valve, which is unlocked by pressing the button. In most cases, it is necessary to put pressure on it with a tangible effort, which some users present as a minus.

Possible leaks in the area of the cap thread are also classified as negative aspects of the Rondell RDS-836. This defect is not of a mass nature, but it takes place in some copies of the model. Another limiting factor is the ban on taking a mug of "bath procedures" in the dishwasher. Otherwise, the product fully fulfills every penny spent, delighting with warm drinks or soft drinks "on the go", regardless of the weather outside the window.

Display for displaying parameters, automatic plastic feeding, smooth speed adjustment, working with ABS and PLA-plastic, auto-off after 2 minutes of inactivity.
 
 
Mediocre build quality, short cord.
 

The Myriwell RP100B DIY pen "writes" instead of the traditional paste with plastic threads, using non-toxic biodegradable PLA material and high-strength ABS plastic.

Kids, as the main target audience of the pen, will be able to master the principles of drawing with it in a matter of minutes. Suddenly, a mini-screen comes to the rescue to display the type of selected plastic and its heating temperature. Consumables for drawing should have a thread diameter of 1.75 mm, and at the outlet of the nozzle of the gadget, the plastic lies in an even line with a thickness of up to 0.7 mm.

The plastic supply of the model is adjusted automatically. It is enough just to hold down the button selected for this good cause. Another button on the "body" of the handle is responsible for the reverse function. Finally, the feed rate of the plastic thread is regulated by a separate slider. The faster the motor buzzes, the thinner the output line will turn out, and vice versa — at low speeds, the pen draws with a thick layer of plastic.

Myriwell RP100B receives power from a stationary 230 V network via a complete block. Its disadvantage is a short cord. In contrast to what has been said, it is worth noting the function of auto-disconnecting the handle after 2 minutes of inactivity, which raises the level of safety of operation of the gadget to a new qualitative level. Having a democratic price tag, the pen is good in the role of a serious tool for large-scale drawing.

Excellent sound, built-in microphone with noise reduction, IPX7 protection, compact size.
 
 
It is not possible to control music from the speaker.
 

When it comes to high-quality portable speakers, JBL Bluetooth speakers are almost impossible to find. The smallest, but by no means the worst instance in the line of the American brand is the "baby" JBL Go 2, addressed to everyone.

The beauty of the column is that it has been assigned an IPX7 protection class. This means that the model is able to survive a sudden rain on a picnic or a short-term immersion in water without the slightest twinge of conscience. Also, the most suitable place for a portable gadget is on the beach or by the pool. With mobile "handsets", the speaker communicates via Bluetooth 4.1 protocol within a radius of 10 m, and a 3.5mm cut is provided on board for wired connection to an audio signal source.

Despite the ultra—compact dimensions (71x86x32 mm), the "baby" plays very well — without hoarseness, snuffling and with a more pronounced bassiness than the first generation JBL Go Price from 999 up to 1 429 ₴. Of course, she won't show herself in the dubstep genre, but with dance and pop music, the column handles with the "five", albeit with a slight minus.

Technically, the model is based on a 40-millimetre dynamic emitter with a power of 3 watts. The additional assets of the JBL Go 2 have a built-in microphone with a "noise reduction". The speaker receives power from a 730 mAh battery, which is strong enough for a 5-hour marathon of playing music tracks. Serious competition of the model is imposed only by Xiaomi Mi Bluetooth Speaker , armed with a control panel and a card reader. But if the priority is water protection and the big name of a proven brand — JBL Go 2 is your everything!

 
Battery power, mobility, lighting brightness adjustment, colour temperature selection, touch control, colour indication of the battery level.
 
 
Low maximum brightness.
 

The Austrian brand EGLO has eaten more than one dog in the lighting industry. Among the desktop models, the LED lamp La Seca 97045 with a whole galaxy of highlights is of great interest.

The key "trick" of the table lamp is working from its own battery with a capacity of 1200 mAh without physical connection to the outlet. In addition, due to its compact size and folding hinge, the lamp takes up a minimum of space in the transport position, being a kind of road version of a portable light.

An LED module is integrated into the "head" of the product with support for three-stage brightness adjustment and the ability to select a colour temperature in the range from 3000K to 5000 K. Someone likes warm tones, others prefer white light — you can vary the flow temperature according to user preferences by tapping on the touch control panel at the base of the lamp body.

You can't call the model particularly bright — at the maximum it gives out a luminous flux of up to 400 lm. However, this stone in the garden EGLO La Seca 97045 is completely leveled by the mobility of the lamp. An additional plus in karma is a colour indication of the level of the remaining battery charge. The blue stripe on the "leg" of the device informs about the need to recharge the battery, the green one glows when the battery is charged, and the red one shines during the process of "refueling" the tanks with energy.
