As smartphones, tablets, and wireless gadgets become indispensable, so does the need for portable charging solutions. That is why power banks are one of the most in-demand tech accessories and a massive resale opportunity for 2025.

Whether you're an electronics store owner, Amazon FBA seller, or distributor, buying wholesale power banks can unlock high margins with low overhead. But success in this space is not just about finding a cheap product; it’s about choosing the right supplier, pricing strategically, and selling through the right channels.

This guide covers everything you need to know, from finding a bulk power bank supplier to understanding market trends, and pricing per unit, so you can thrive in the power accessory business.

Why Power Banks Are a Smart Product to Resell in 2025

Let’s start with the numbers.

The power bank market is growing fast. It's expected to increase from $18.59 billion in 2024 to $20.56 billion in 2025, with a yearly growth rate of 10.6% according to Fortune Business Insights.

This growth is primarily fueled by:

● Increasing smartphone dependency

● Rise in remote and hybrid work culture

● Frequent travel and outdoor lifestyles

● Demand for high-capacity fast-charging solutions

Power banks are not just a passing trend; they are a utility. And for resellers, they offer a low-cost, high-turnover product category that doesn’t expire, requires minimal maintenance, and appeals to both B2B and B2C buyers.

How to Choose a Bulk Power Bank Supplier

Did you know that your supplier doubles up as your business partner? Well, the right supplier can mean fewer returns, better customer satisfaction, and stronger margins.

Here’s what to look for in a bulk power bank supplier:

1. Certifications and Compliance

Before getting into an agreement with a supply, check that the manufacturers meet CE, FCC, RoHS, and UN38.3 certifications. These formalities prove the product is safe, legal, and shippable worldwide.

2. Battery Type & Capacity Options

To be on the safe side, stick to lithium-polymer batteries. These batteries are more compact, stable, and offer longer shelf life than older lithium-ion types. Also, diversify your stock: offer options from 5,000mAh for casual users to 20,000mAh for power users.

3. Customization & Branding

Look for suppliers that allow:

● Logo printing

● Custom packaging

● White labeling

If you’re serious about building your own brand, these features are essential.

4. MOQ (Minimum Order Quantity)

Not all resellers can start with 10000 units Good suppliers like Pisen offer flexible MOQs making them ideal for both small retailers and large distributors.

Understanding Power Bank Price Per Unit

Profit begins with smart sourcing. Here’s how power bank price per unit typically breaks down:

Capacity	Features	MOQ	Price per Unit (Est.)
5,000mAh	Standard USB	100+	$4.50 – $6.00
10,000mAh	Fast Charging	200+	$6.50 – $9.00
20,000mAh	PD + USB-C Output	500+	$9.50 – $14.00

Factors that impact pricing include:

● Charging technology (PD, QC 3.0, wireless)

● Input/output ports

● Branding or customization

● Packaging

Pro tip: To protect your margins, always request a tiered pricing sheet and factor in shipping, import duties, and marketing costs.

Where to Sell: High-Profit Channels for Power Bank Resellers

You have got inventory, but now how do you sell? These are the top-performing channels in 2025:

Online Marketplaces (Amazon, eBay)

Pros: Huge audience, fast setup
 Cons: High fees, saturated market

If you choose Amazon FBA, make sure your product passes battery shipping regulations and includes proper labeling.

Your Own E-commerce Store

A branded Shopify or WooCommerce store gives you more control over pricing, design, and customer relationships.

Combine power banks with wireless earbuds or charging cables to boost AOV.

B2B and Institutional Buyers

Sell directly to:

● Schools and universities

● NGOs and aid organizations

● Travel and events companies

● Local retailers and gift shops

These clients often buy in bulk and prefer local suppliers with quick turnaround.

How to Market Your Wholesale Power Banks

Even if your product is solid, it won’t sell itself. Here’s how to build trust and drive volume:

Create Educational Content: Help your audience make informed decisions. Write how-to blogs (like this one), product comparison guides, or even a complete reseller guide for electronics.

Emphasize Safety & Warranty: Battery safety is a top concern. Highlight your product’s certifications, fire protection features, and warranty period.

Use Social Proof: Request testimonials or case studies from happy resellers or end-users. This builds authority and encourages trust with new buyers.
