Power Bank with Logo: How to Choose Capacity and Safety
A guide to power banks with logo printing: what mAh capacity you need, what W and Wh mean, which certifications to ask for, and how much logo printing costs.
In practice, power banks with logo printing for corporate gifts are most often chosen in the 5,000–10,000 mAh range: 5,000 mAh charges an average smartphone about once, 10,000 mAh roughly twice, while 20,000 mAh models weigh 350–450 g and are priced more for VIP gifts. Rough prices with logo printing start from about 12 EUR per piece (5,000 mAh, from 50 pcs) up to 55–70 EUR for 20,000 mAh branded models, excl. VAT. Preparing the artwork and production usually takes 5–10 business days.
How many mAh do you actually need
The mAh figure printed on the casing isn't what actually reaches your phone. Due to internal voltage conversion, real-world output is around 60–70% of the rated capacity. This means a 10,000 mAh power bank delivers roughly 6,500–7,000 mAh of usable energy — two full charges for a phone with a 3,500 mAh battery.
- 1,200–5,000 mAh — compact models for a pocket or as an add-on to a conference bag. For example, *Span 1200 mAh* or *Asama 5000 mAh Type-C made from recycled plastic*.
- 5,000 mAh magnetic — attach to the back of the phone without a cable. *Avis 5000 mAh made from RCS recycled aluminium*, *SMART 5000 mAh with strap*.
- 8,000–10,000 mAh — the most popular choice. *Plate 8000 mAh aluminium*, *Adhil 10,000 mAh 10 W with 2 built-in cables*, *Acrab 10,000 mAh 15 W magnetic wireless with 20 W PD*, *Avis 10,000 mAh magnetic*, *Xtorm FS510 Fuel Series 10,000 mAh 20 W*.
- 20,000 mAh — for long business trips and fieldwork: *Xtorm Go2 20 W 20,000 mAh*, *Xtorm FS520 Fuel Series 20,000 mAh 35 W*.
W and mAh — two different measures
mAh shows how much energy is stored. Watts (W) show how fast it flows out. A 10 W output charges a phone to 50% in roughly 60–70 minutes; 20 W with Power Delivery takes about 30 minutes. If the gift is for people working with tablets or laptops, look for 35 W or more — for example, the *Xtorm FS520* with a 35 W output. The *Xtorm 45W NextGen* and *Xtorm 70W NextGen* wall chargers also pair well as a set with a power bank.
Model comparison and approximate prices
| Model | Capacity | Output | Printing method | Price from (excl. VAT) |
|---|---|---|---|---|
| Span 1200 mAh | 1,200 mAh | ~5 W | Pad printing, digital sticker | ~7 EUR |
| Asama 5000 mAh Type-C | 5,000 mAh | ~10 W | Digital printing, doming sticker | ~13 EUR |
| SMART 5000 mAh magnetic | 5,000 mAh | 15 W wireless | Digital printing, pad printing | ~17 EUR |
| Plate 8000 mAh aluminium | 8,000 mAh | ~10 W | Laser engraving | ~19 EUR |
| Adhil 10,000 mAh with 2 cables | 10,000 mAh | 10 W | Digital printing, pad printing | ~22 EUR |
| Acrab 10,000 mAh wireless | 10,000 mAh | 15 W + 20 W PD | Digital printing, sticker | ~29 EUR |
| Xtorm FS510 10,000 mAh | 10,000 mAh | 20 W | Laser engraving | ~34 EUR |
| Xtorm FS520 20,000 mAh | 20,000 mAh | 35 W | Laser engraving | ~55 EUR |
Prices are indicative for an order of 50 pcs with a single-colour logo. The exact price depends on quantity, printing method and number of colours — at 250–500 pcs the difference can be 15–25%.
Safety: what to ask for before ordering
A lithium battery must carry CE marking, a UN38.3 transport test report, and protection electronics against overcharging, overheating and short circuits. These documents are available for the models in our catalogue — request them if the gifts are intended for a public event or a municipal project.
Practical safety guidelines:
- Air travel. Power banks may only be carried in hand luggage. The limit is 100 Wh. 10,000 mAh ≈ 37 Wh, 20,000 mAh ≈ 74 Wh — both are allowed.
- Storage. Do not store below 0 °C or above +35 °C. If gifts are stored for longer than six months, it's recommended to charge them to ~50% every 6 months.
- Casing. Aluminium casing (*Avis*, *Plate*) dissipates heat better and looks good for longer than plastic, but scratches more easily.
- Wireless charging certification. If choosing a magnetic model, make sure it's Qi-certified — otherwise some phones won't recognise it.
How the logo looks on a power bank
Laser engraving is the only option for Xtorm models. The result is a matte, permanent image in the shade of the casing. It's single-colour, with no halftones, so a thin line under 0.3 mm may disappear.
Pad printing suits one- or two-colour logos on plastic. Digital printing and full-colour doming stickers allow full-colour images with gradients — used for *Asama*, *Adhil*, *Acrab* and *Span* models when the logo is multicoloured or includes a photo element.
Send files as vector graphics (.ai, .eps, .pdf), colours in CMYK or with specified Pantone codes. Before production, we prepare a visual with logo placement and size in millimetres.
Timelines and quantities
The standard turnaround is 5–10 business days from design approval. Laser engraving is usually faster than doming stickers, which require resin curing time. Urgent jobs can be arranged by separate agreement.
The minimum quantity with logo printing starts from 25 pcs, though it's more cost-effective from 50 pcs. If you only need a few pieces for a gift, we can also supply them unprinted or with a sticker.
The full range of promotional products with logo and other categories — printing services — is available on the website. Power banks are often ordered together with thermal mugs/bottles or tote bags, so the whole gift box matches in style.
Frequently asked questions
What mAh power bank is optimal for a corporate gift?
10,000 mAh is the most common choice — two phone charges, a weight of about 200 g, and a price from around 22 EUR with logo printing. 5,000 mAh suits mass events where compactness and budget matter most.
Can a power bank with a logo be carried on a plane?
Yes, but only in hand luggage. Up to 100 Wh is allowed without separate approval; 10,000 mAh is approx. 37 Wh, 20,000 mAh approx. 74 Wh, so both fall within the limit.
Which printing method is the most durable?
Laser engraving — it doesn't wear off or fade, as the image is engraved into the material. For full-colour logos, a doming sticker with a transparent resin coating is the most durable.
How long does an order take?
Usually 5–10 business days from the moment the visual is approved. For urgent jobs, we agree on the timeline separately.
Can I order just 10 pieces?
Yes — with logo printing the minimum is usually 25 pcs, but we handle smaller quantities individually, for example with a digital sticker. At larger volumes, the price per piece drops significantly.
Do the power banks come with a warranty?
Yes, the models in our catalogue come with a manufacturer's warranty — 12 or 24 months depending on the model. We send documentation and CE/UN38.3 certificates upon request.
