I’ve been testing battery-powered espresso makers for the previous couple of months, chasing one easy factor: correct espresso with no wall outlet.
The MHW-3Bomber X-Press58 is the primary one that actually seems like “residence machine power” in a journey physique. It has an actual 58 mm portafilter, so all of your baskets, tampers, and puck screens drop proper in.
Heads up: The assessment unit was supplied by the model. They’ve had no affect on my testing process.
Fast Take
- A premium, battery-powered espresso maker constructed round a real 58 mm portafilter.
- Finest-in-class warmth and battery
- Plentiful accent bundle.
- However steep value!
First Impressions
The X-Press58 truly seems and feels loads like most different battery espresso makers comparable to these from Outin.
So it’s bought that thermos-inspired look. Nevertheless this explicit mannequin is available in a discrete matte black with minimal branding, making it a bit extra glossy and trendy.
I anticipated that the efficiency may be comparable, however after diving into testing and brewing, I spotted that there was extra energy below the hood.


In temperature exams, I repeatedly noticed 96 °C within the reservoir. That is 3-4 levels larger than its rivals – which means medium/gentle roast pictures will style higher.
The heating time can also be very quick, round a bit lower than 3 minutes, relying on how a lot cost the battery holds.
| Shot quantity | Temp (°) | Time to warmth up |
|---|---|---|
| Shot #1 | 95.4 | 2 minutes 35 seconds |
| Shot #2 | 96.7 | 2 minutes 40 seconds |
| Shot #3 | 96.0 | 2 minutes 55 seconds |
| Shot #4 | 96.7 | 2 minutes 58 seconds |
Journey bundle is good though on the cumbersome aspect. And as you’d anticipate from this model the equipment are top-notch.


How It Matches within the Market
Most moveable items use smaller baskets and really feel power-constrained.
However right here you get a pro-size 58 mm and severe battery capability at 13000 mAh.
It’s the priciest possibility among the many battery espresso makers, round double the value of many rivals.
However it’s simple to see the place the cash goes with that luxurious accent bundle and ample battery life.
Should you already personal 58 mm gear, compatibility swings worth again in its favor.


(For context, the 58 mm ecosystem is the preferred espresso commonplace, which incorporates many residence machines and equipment, comparable to Gaggia Basic Professional, Aptitude 58, Rancilio Silvia, Breville Twin Boiler and extra).
What I Appreciated
- 58 mm compatibility means immediate entry to IMS, VST, puck screens, and so forth.
- Actual thermal efficiency: 96 °C measured in water tank repeatedly
- Quick heat-up, about 2:47 to first shot from room temp water
- Included funnel + calibrated tamper are extraordinarily good
- Sturdy journey case
- Comes with a weird puck blower that replaces the knock field. It truly works and is enjoyable to make use of!
What I Didn’t
- Fastened pre-infusion, you can’t disable it, which limits geeky profiling experiments
- The included stand is on the decrease aspect. Should you use a scale there’s not a lot clearance for an espresso cup
- You purchase the entire package, even in case you already personal nicer tampers or a case, so that you pay for duplicates
- Premium value
- No capsule possibility, not like with Outin and others
Unresolved Questions
- Can you utilize this as your every day driver for years? Value-wise it’s near actual espresso machines. Efficiency-wise it would truly beat lots of them, because it’s extra temperature steady than machines like Gaggia Basic Professional and Rancilio Silvia. However is it a viable possibility in the long term or will efficiency degrade with prolonged use?
First Sip Verdict
If you need essentially the most “pro-like” espresso from a battery unit, that is the one which lastly delivers. Thermal energy, steady brew temps, full-size baskets, and a no-drama workflow add as much as reliably wonderful pictures. It isn’t low cost, and the fastened pre-infusion plus that brief stand are actual quirks.
Nevertheless, for capsule enjoyers and informal espresso drinkers who respect darkish roasts, a less expensive possibility can be simply nearly as good.
