Output watts and milliamp hours answer different questions
Two numbers do most of the work in this category, and they are not interchangeable. Output describes how hard a charger can push charge into a device; capacity describes how much charge a power bank stores. Buyers who mix them up end up with a heavy pack that refills slowly, or a small charger that cannot handle a laptop.
DeWalt sells chargers only, with top output of 1,800 W across its power stations, which sits at the extreme end of this category. INIU's top output is 140 W and mfish's is 240 W, both aimed at phones, tablets and laptops. Across the brands tracked here, top output runs 15 to 22,000 W, so there is a wide gap to close before you compare anything else.
Check what each brand charges fastest
Output is a ceiling rather than a promise, so the next check is the charging standard. INIU and mfish both offer Gan, which covers the main phone and laptop fast-charging formats. DeWalt does not offer Gan and concentrates on its own charger range, so it fits a different buyer entirely.
A quick way to use this: pair the fast-charging answer with the output figure. A Gan charger at 240 W will refill a phone far faster than a charger with the same headline watts but no fast-charging support.
Capacity for people away from a socket
On stored charge, Akkuk.hu tops out at 25,000 mAh and INIU matches that with 25,000 mAh, while mfish goes further at 40,000 mAh. More capacity means more full charges for a heavy phone user and more headroom for a tablet, though the figure says nothing about refill speed or how many ports work at once.
Read capacity and output as a pair rather than in isolation. mfish combines 40,000 mAh with 240 W, a stronger showing than capacity alone. Akkuk.hu lists charger, power bank and cable in one shop, so a desk charger and a travel pack can arrive together. INIU adds a wireless charger to a similar range.
Starting prices, currency and delivery
Treat these as product prices rather than plans, and check the currency in each figure. Akkuk.hu lists from HUF 1,990, INIU's chargers start at €10.99 and mfish's fast chargers at $9.99. Starting prices across the category run €5.25 to €1,139.17, so the cheapest model tells you little about what the mid-range units cost.
Delivery can move the total. Akkuk.hu offers free delivery above HUF 20,000, so a single small charger can still arrive with a charge added to the shelf price. Akkuk.hu also offers click and collect, and it does not offer trade in.
Warranty length and return windows
Warranty is the widest spread of all. Akkuk.hu covers products for 1 to 3 years and allows returns within 14 days, INIU lists 3 years and DeWalt lists 3 years. DeWalt's cover applies to its own charger range, a different purchase from a travel power bank.
Warranty terms across the category run 1 year to lifetime, a spread worth checking against whichever brand you pick. A longer term carries more weight for a pack used daily, because stored capacity fades over time and a warranty is what covers a unit that stops holding charge.
Where each brand ships and who to call
Coverage decides whether a good price is usable. Akkuk.hu ships within HU, AT and BE, DeWalt across US, CA and MX, INIU within US, CA and MX and mfish to AE, AT and AU. Confirm your own country appears in the list before weighing price.
Support matters when something arrives faulty. Akkuk.hu works through email, phone and a help center (email, phone and help centre). DeWalt adds live chat to those channels (email, chat and phone), and INIU adds a community space alongside email, phone and a help center (email, phone and help centre).
Company age is a rough reliability signal. DeWalt has traded since 1924 and Akkuk.hu since 2005. Headquarters sit in HU for Akkuk.hu, IE for INIU, and US for DeWalt and mfish alike.
Where each brand lands
For raw output, DeWalt leads on 1,800 W but is limited to chargers. For the best balance of stored charge and refill speed, mfish pairs 40,000 mAh with 240 W and Gan. INIU matches Akkuk.hu on capacity, adds a wireless charger and starts at €10.99. Akkuk.hu is the one to watch on delivery, with a starting price of HUF 1,990 and free delivery above HUF 20,000.
