Detailed overview: Rugged Xtorm 40,000mAh power bank
The Xtorm XR204 belongs to the Xtreme Series, the Dutch brand's outdoor line specialised in rugged accessories for mobile devices. With 40,000mAh (154Wh) on tap, it is one of the most generous power banks in the catalogue, built to last several days off the grid, whether on an expedition or during a power cut at home.
On the charging side, the XR204 relies on three complementary outputs: a first USB-C Power Delivery port that reaches 100W, enough to fast charge a laptop or tablet, a second USB-C at 20W, and an 18W USB-A Quick Charge 3.0 port. All three ports can be used at the same time to power up to three devices at once, with pass-through charging so a device can charge while the power bank itself is being topped up. On the input side, a USB-C port accepts up to 65W, refilling the battery in about 3.5 hours.
The recycled polycarbonate and TPU housing carries an IP64 rating: shockproof, dust and splash resistant, with an adjustable strap handle to clip it to a backpack or carry it by hand. A smart display shows the remaining battery percentage and the output power of each port in real time, handy for keeping an eye on charging at a glance. The built-in flashlight offers four modes (spotlight, ambient lantern, flash and SOS), a genuine bonus for a campsite or a night time fix.
At 809g and 140 x 70 x 90mm, the XR204 is nothing like a pocket power bank: it is an emergency energy block to slip into a backpack or keep in the car. Its 154Wh capacity exceeds the 100Wh usually allowed in cabin baggage without formalities, worth checking with your airline before travelling. For camping, van life, job sites or simply guarding against a power cut, this large, rugged battery with built-in screen and flashlight ticks every box for outdoor versatility.

Comparison
Around £100 to £180, the Xtorm XR204 goes up against several sought after high capacity power banks, in searches such as "best camping power bank" or "100W power bank review". Here is how it compares with three alternatives: the Ugreen 300W 48000mAh, far more powerful but noticeably heavier; the Anker Prime 26250 (300W), a light premium option with less endurance; and the Anker A1695 (165W), more compact thanks to its built-in cables.
| Criterion | Xtorm XR204 | Ugreen 300W 48000mAh | Anker Prime 26250 (300W) | Anker A1695 (165W) |
|---|---|---|---|---|
| Capacity | 40,000mAh (154Wh) | 48,000mAh (154Wh) | 26,250mAh (≈ 100Wh) | 25,000mAh (90Wh) |
| Max power | 100W (USB-C PD) | 300W (USB-C 140W) | 300W (USB-C 140W) | 165W (USB-C 100W) |
| Display and light | Smart display, 4-mode flashlight | LCD display, LED light | LCD display, no light | LCD display, no light |
| Durability | IP64 (shock, dust, splash) | Not rated | Not rated | Not rated |
| Weight | 809g | ≈ 1637g | 600g | 595g |
| Observed price | ≈ £105 | ≈ £95 | ≈ £170 | ≈ £95 |
In short, the Xtorm XR204 remains the most versatile choice for outdoor use and home backup thanks to its IP64 rating and built-in flashlight, two features none of the three rivals offer. The Ugreen 300W 48000mAh wins by a wide margin on raw power and capacity, but in a housing nearly twice as heavy. The Anker Prime 26250 and A1695 are lighter and more powerful in watts, but with lower capacity, no light and no rated protection against the elements: solid picks for the city, less so for the field.
Our tester's review: Guillaume Hoarau
We took the Xtorm XR204 on a weekend hiking trip and it quickly earned its spot in the bag, clipped on by its adjustable strap handle. First impression: this is no pocket power bank, at 809g you feel like you're carrying a genuine energy reserve rather than an everyday accessory. And that's the trade-off it makes no secret of: its 40,000mAh kept our phones and camera topped up for three days without a single recharge. The display is very clear, showing remaining percentage and per-port output at a glance, a real step up from plain LEDs. The 100W USB-C port charged a laptop almost as fast as its own mains adapter, without a hitch. The flashlight, with its ambient mode, saved more than one evening at camp. One gripe: the casing stays bulky in an already loaded bag, and IP64 covers splashes, not full submersion. For heading out far and long without compromising on power, this is a safe bet.
