Sharge’s catalogue divides more cleanly than the model names suggest. There are high-output packs built to run a laptop, magnetic batteries built to stick to a phone, and small packs built to disappear in a pocket. Deciding which device you are actually rescuing settles it in one step.
Sharge
Sharge designs and sells portable power and charging gear: high-capacity power banks, magnetic wireless batteries and GaN wall chargers. The Shargeek 170, Shargeek 300 and HyperTower 170 pair 24,000–25,000mAh cells with 170W–300W output and built-in cables, while the ICEMAG and CarbonMag series bring Qi2 magnetic charging with active cooling and carbon-fibre builds. Compact options include the Flow 3 and Flow Mini 2, plus the Discho 3-in-1 foldable station for travel. The brand leans on industrial design, durable materials and fast-charging performance.
Output decides laptops, capacity decides phones
Two numbers do almost all the work here, and people routinely confuse them. Capacity in mAh tells you how much energy the pack holds. Output in watts tells you how fast it can deliver it — and whether it can run a laptop at all. A large-capacity bank with low output will charge a laptop slowly or not at all, which is why the 170W–300W models exist as a separate tier.
If your problem is a phone running flat by the afternoon, capacity and convenience matter and the high-output tier is overkill. If your problem is a laptop on a long travel day, output is the specification to buy on.

The ranges, and who each one is for
Shargeek 170, Shargeek 300 and HyperTower 170 — the laptop tier
These are the models to look at if a laptop is in the equation. Output from 170W to 300W is enough to matter for a working machine rather than trickling it along, and built-in cables remove the most common failure point of a travel kit: the cable you left at home. The trade is size and weight — a 24,000–25,000mAh pack is not a pocket item.
ICEMAG and CarbonMag — the magnetic Qi2 batteries
Qi2 magnetic charging means the battery attaches to the back of a compatible phone and charges it wirelessly, which is genuinely convenient when you want to keep using the phone. Wireless charging generates heat and wastes some energy as a matter of physics, which is why active cooling appears on this line. Choose these for phone-first convenience, not for efficiency.
Flow 3 and Flow Mini 2 — compact everyday carry
Small packs for topping up a phone, sized to actually be carried rather than left at home. This is the range that gets used most, because the best power bank is usually the one in your bag rather than the biggest one on the shelf.
Discho 3-in-1 — the travel station
A foldable multi-device station aimed at travel, so one item in the bag replaces several chargers. Worth considering if you regularly pack a phone, watch and earbuds and are tired of a tangle of plugs.
GaN wall chargers
GaN technology lets a wall charger deliver high wattage in a smaller body than older silicon designs. If you are buying a high-output power bank, check what wall charger you are pairing it with — recharging a 25,000mAh pack from a low-wattage plug takes a long time.
Is it the right pick for you?
You know which problem you are solving. The high-output Shargeek and HyperTower models are a real answer to laptop charging away from a socket, and the ICEMAG and CarbonMag line is a real answer to phone convenience. Built-in cables on the large packs are a practical advantage over rivals.
You want the lightest possible pack for a phone and nothing more — the flagship models are large and heavy by design. Air travel is the other consideration: high-capacity packs run into airline watt-hour limits, which is a planning issue rather than a product fault.
Before you buy, check the watt-hours
- Airlines regulate lithium batteries by watt-hours (Wh), not mAh. The figure is normally printed on the pack itself. As a general rule carriers allow up to 100Wh in carry-on without approval, and 100–160Wh with prior airline approval — always confirm with your specific airline before flying.
- Power banks must travel in carry-on baggage, not checked luggage, on practically every airline.
- Site-wide codes normally reach the whole catalogue, but flagship models in a current sale are the usual exception. Test the code in the cart.
- Codes rotate, so compare the current listings rather than reusing an old one.
Questions buyers ask
Which Sharge power bank is best for laptop charging?
The high-output models — Shargeek 170, Shargeek 300 and HyperTower 170 — are the ones built for it, with 170W to 300W output. Output in watts, not capacity in mAh, is what determines whether a pack can properly charge a laptop.
Does the ICEMAG line support Qi2 wireless charging?
Yes. The ICEMAG and CarbonMag series are the Qi2 magnetic models, and they include active cooling because wireless charging produces heat.
Are Sharge power banks airline safe?
That depends on the watt-hour rating of the specific model and on your airline’s policy, not on the brand. Check the Wh figure printed on the unit against your carrier’s limit, and keep the pack in your carry-on.
What makes CarbonMag different from other magnetic batteries?
Carbon-fibre construction and the Qi2 magnetic attachment are the stated differences, alongside active cooling shared with the ICEMAG line.
Which models include built-in cables?
Built-in cables are described as a feature of the high-capacity Shargeek and HyperTower models, which is one of the practical reasons to pick that tier for travel.
Does Sharge make compact power banks for everyday carry?
Yes — the Flow 3 and Flow Mini 2 are the compact options, sized for a pocket or small bag rather than for laptop duty.
How this guide was put together. This is a research-led buying guide, not a hands-on test. It is built from the brand’s own catalogue and product line documentation, the questions shoppers ask most often, and the offer terms published at the time of writing — we have not personally used every product named here, and we say so rather than implying otherwise. Discounts and product availability change without notice, so check the live price and the offer terms at checkout. If you buy through a link on this page we may earn a commission at no extra cost to you, and that never changes which products we cover.
