On a trip, charging the drone alone is not enough. Flight batteries, the controller, and your smartphone all need power, and an FPV kit also needs goggles. Many modern consumer DJI devices can share a USB-C PD power source. However, the power required to charge the drone, accessories, and charging hub differs. This guide covers current and recent Mini, Lito, Air, Mavic, Flip, Neo, and Avata series: what to connect, which power supply to choose, and how to build a charging kit

The arrival of high-performance processors from NVIDIA, AMD, and Apple Silicon, together with large amounts of shared memory, has made local AI accessible in different formats: from laptops to compact home workstations. They share an architecture in which the processor and integrated graphics accelerator use the same large pool of high-speed memory. This allows a large, capable LLM model to stay close to the compute units, without constantly transferring parts of it over a sl

The included charger charges your smartphone quickly as long as it is available and working. But what should you choose if the adapter is lost, stops working or you need an extra charger for the car and travel? For OPPO, OnePlus and realme, the choice depends on more than the power rating printed on the case: the protocol, port and cable all matter. VOOC, SuperVOOC, Dash, Warp and Dart: related technologies Fast charging on smartphones from these brands relies on the VOOC and

When traveling, it is convenient to use one charging kit for your camera, laptop, and smartphone rather than carry a separate adapter for each device. But will your laptop charger work with your camera, will a power bank last for the trip, and can you keep shooting while connected? The answers depend on your model and chosen power setup, so it is best to check before you leave. However, having USB-C does not guarantee charging support. The connector may be used only for data

Starlink can be powered by a mains USB-C charger, a power bank or a portable power station. Compatibility depends on the terminal model, the charger's output mode and the cable. Starlink Mini officially supports power via USB Power Delivery. Here is what you need to use it at home, in a car or at a campsite, and how much energy to store for several hours of connectivity. Which Starlink models support USB-C PD The Starlink Mini specification requires a USB PD source rated at l

A good USB-C charger, such as the Apple 140W, can serve you for years. The only thing that annoys you about it is a single charging port. While it is busy with a laptop, your smartphone has to wait its turn, even though the charger has enough power for both. Buying a new multi-port charger just for a second port is not always sensible. There is a simpler solution: an active 2-in-1 Y-cable that shares the power of one port between two devices. When one port is not enough Here

An external SSD, a monitor, and laptop charging can all use the same USB-C connector, but their cable requirements differ. Choosing a cable means understanding not just USB and Thunderbolt speeds, but also length, compatibility, and what “active” means. Especially if you want to make use of your devices’ capabilities, rather than simply find plugs that fit. USB speeds and their names USB-IF, the organization that develops the standard, identifies five data speeds as of 2026:

A cable charges your laptop reliably, yet copying files through it turns out to be unexpectedly slow. Another looks the same but will not enable the fast charging mode you need. The labels on the packaging do not always explain these differences: power, data speed, and charging quality depend on different cable characteristics. How a charging cable is built A USB-C cable consists of several groups of wires, and each has its own job: VBUS and GND - power wires. The charging cu

Image source: Apple After buying an iPhone 18 Pro or Pro Max, it is easy to start thinking about a new charger too: the description now includes different power ratings and the term AVS. But you already have a working USB-C adapter at home, and want to understand what replacing it would actually give you. Especially if a quick top-up before heading out matters more than simply charging overnight. What Apple's power figures mean In Apple's information sheet, the ranges are 4.5

A smartphone, tablet, and laptop take up several sockets, and travelling means carrying a whole set of adapters. You would like to replace them with one charger, but questions arise: will it work with every device, retain fast charging, and provide enough power when they are connected at the same time? With matching USB-C connectors, the choice looks simpler than it proves to be in practice. In practice, there are three separate questions: is the connection safe, will chargin

When the charger supplied with your smartphone goes missing or no longer meets your needs, choosing a replacement raises doubts. Does the adapter need to be from the same brand, will fast charging still work, and could one power supply serve both your smartphone and laptop? It helps to understand what actually depends on the manufacturer and what comes down to compatibility between specific devices. Below, we will look at the limitations of original chargers, which universal

You have a powerful laptop charger to hand, but need to connect a smartphone. The connector fits, yet the figures on the adapter are much higher than you are used to, raising a doubt: could that extra power be too much for a small device? To assess this connection, it helps to understand what happens between the charger and smartphone after you plug in the cable. Below, we explain how this works, where the real risk lies, and why extra power headroom is a sensible choice rath

Google Pixel 11 Pro and Pixel 11 Pro XL. Source: Google A powerful USB-C charger with PPS support seems a suitable choice for a Pixel Pro XL, yet the smartphone may charge more slowly than expected. Meanwhile, the adapter’s specifications look convincing. The Pro XL models have particular power requirements that are easy to miss if you look only at total wattage and familiar protocol names. What PPS is and why different ranges exist PPS (Programmable Power Supply) is a USB Po

If you are flying to China with a power bank, the usual limit of up to 100 Wh is not enough. On a domestic flight within China from June 28, 2025, the device must have a clear CCC mark and must not belong to a recalled model or batch. The rule is checked at pre-flight security: an absent or illegible mark means the power bank cannot enter the cabin. CCC is not an international aviation certificate. It is mandatory Chinese product certification. It matters to travelers chiefly

Image source: Apple Newsroom The standard MacBook Pro 16 charger is not convenient in every situation: at home you may want to connect a smartphone to the same adapter, in the car you need another power source, and away from a socket a power bank comes in handy. When putting this kit together, it is important to retain the laptop’s charging capabilities. This article brings together tested options for these scenarios and suitable cables. Below, we take a closer look at the ch

Portable gaming consoles and handheld gaming PCs let you play at home or on the go. However, their high performance requires a sufficiently powerful power source. A smartphone charger may be too weak: the console may charge slowly, stop charging while you are playing, or limit its performance. Most modern handheld gaming devices charge through USB-C. However, a USB-C port alone is not enough. The charger must support USB Power Delivery and provide sufficient power through a s

Two USB-C chargers with the same wattage on the box can behave differently with your laptop and smartphone. Connecting a second device changes the result again. To choose a convenient adapter for home or travel, it is worth understanding which specifications will actually affect how it works with your set of devices. Just a few years ago, things were simpler: a smartphone usually came with a charging adapter in the box, and a laptop had its own power brick. Today, chargers mo

Topping up a smartphone on the go and working on a laptop away from a socket call for different power banks. A large capacity looks appealing, but you also need to consider weight, charging speed, and convenience. The choice becomes clearer when you start with your own needs, then examine the specifications of suitable models. That is why capacity in mAh is an important parameter for a power bank, but not the decisive one. By itself, it does not answer the main question for m

The original charger charges a Xiaomi, Redmi, or POCO smartphone quickly, but is not always convenient for other devices. You would like to replace it with a multiport adapter or power bank while retaining the familiar charging speed. For these smartphones, choosing one involves more than wattage: you also need to understand charger compatibility and which cable is suitable. Modern smartphones from the related brands Xiaomi, Redmi, and POCO are charged primarily via the propr

Image source: Apple Newsroom For an iPhone or iPad, you want a charger that does more than fit the connector: it should let you use your model’s fast charging capabilities. The choice becomes more complicated if you still have Lightning devices at home, have added newer USB-C models, or need one adapter for several Apple gadgets. Understanding power requirements and the differences between cables helps here. Apple Smartphones 2025-2026 (September): iPhone 16e (2025) supports
